• Insulated (plastic-coated) wire
• A 4.5-volt or 6-volt battery
• A switch made from a paperclip and two thumbtacks attached to a block
• A small compass

Steps to Make the Electromagnet:

1. Wrap the Wire: Take the insulated wire and wrap it around the cardboard tube.
2. Connect the Battery: Attach one end of the wire to the positive (+) side of the battery and the other end to one side of the switch. Then, connect a wire from the other side of the switch to the negative (-) side of the battery.
3. Place the Compass: Slide the small compass into the middle of the cardboard tube. Make sure it can move freely.
4. Use the Paperclip as a Switch: Position a paperclip close to the thumbtack to make a simple switch. You can swivel the paperclip against and away from the thumbtack to open and close the electric circuit.
5. Observe the Compass: Watch what happens to the compass needle as you open and close the circuit. When you close the circuit (by touching the paperclip to the thumbtack), the electric current flows through the wire, creating a magnetic field. This makes the compass needle move. When you break the circuit (move the paperclip away from the thumbtack), the magnetic field disappears, and the compass needle returns to pointing north.

Helpful Tips

Requirement 5: Battery And Electric Bell

What You Need To Do

Make a simple drawing showing how a battery powers an electric bell. Label the main parts and describe what each component does in the circuit.

Helpful Tips

The diagram presents an electric vibrating bell setup for the Electricity merit badge . To understand its functionality, let’s follow the path of the electric current:

1. Pushing the button allows current to flow from terminal A to the electromagnet, labeled F.
2. The current then travels to a moving contact, C, and proceeds to contact post D, finally exiting through terminal E.

Now, how does this current make the bell ring?

1. As you press the button, electromagnet F attracts an iron armature, labeled B.
2. This armature has two attachments: the moving contact C and a hammer, H.
3. The hammer strikes a gong or bell, producing the ringing sound.
4. As the armature is drawn towards the magnet, the contact C is pulled away from post D, breaking the circuit and cutting off the current.
5. When the current stops, the electromagnet loses its magnetic force. A return spring, G, then pulls the armature and contact C back towards post D.
6. Once contact C reestablishes connection with post D, the current flows again, and the cycle repeats. This rapid repetition creates the continuous ringing or vibrating sound.

Helpful Tips

• A battery provides the electrical energy for the circuit.
• Wires carry electric current between the components.
• A push button switch starts the flow of electricity when pressed.
• An electromagnet becomes magnetic when current flows through it.
• The armature is a metal piece that moves toward the electromagnet.
• A hammer attached to the armature strikes the bell or gong.
• A contact point opens and closes the circuit during operation.
• A spring pulls the armature back after the circuit opens.
• The repeated opening and closing of the circuit creates the ringing sound.
• Label each part clearly on your drawing so the current path is easy to follow.

• A small light bulb or motor
• Insulated wires with clips or connectors
• A sliding contact (such as a metal washer or paperclip)

Steps to Build the Rheostat:

1. Create the Resistive Path: Stretch the resistive wire in a straight line or coil it securely around a non-conductive base, like a piece of cardboard.
2. Connect the Circuit: Attach one end of the resistive wire to the positive terminal of the battery and the other end to the light bulb or motor.
3. Add the Sliding Contact: Place the sliding contact on the resistive wire. This will allow you to change the length of the wire in the circuit.
4. Complete the Circuit: Connect the other terminal of the light bulb or motor to the negative terminal of the battery.

Move the sliding contact along the resistive wire. As you change the length of wire in the circuit, the resistance increases or decreases. This will make the light dimmer or brighter, or the motor spin faster or slower.

Helpful Tips

• A rheostat controls current by changing resistance.
• More resistance reduces current flow.
• Less resistance allows more current to flow.
• A rheostat can make a light dimmer or brighter.
• It can also change the speed of a small motor.
• Resistive wire is commonly used in simple rheostats.
• A sliding contact changes the amount of resistance.
• Moving the contact changes circuit performance.
• The effect should be visible while the circuit is operating.
• Secure all connections before testing.

Requirement 10d: Single-Pole, Double-Throw Switch

What You Need To Do

Build a single-pole, double-throw (SPDT) switch and show how it directs electricity between two different circuits.

What You’ll Need:

• A non-conductive base (such as cardboard or wood)
• Three metal contacts (like small screws or tacks)
• A movable lever (like a paperclip or metal strip)
• A battery
• Two light bulbs or other small loads
• Insulated wires

Steps to Build the SPDT Switch:

1. Attach the Contacts: Secure three metal contacts to the base in a triangle or straight line. These will serve as the connection points for the switch.
2. Create the Lever: Attach the movable lever to the middle contact so it can pivot to touch either of the outer contacts. This allows the circuit to switch between two outputs.
3. Connect the Circuit:
   • Connect the battery’s positive terminal to the middle contact (common terminal).
   • Attach each outer contact to one of the light bulbs.
   • Connect the other terminals of the light bulbs to the battery’s negative terminal.

Move the lever between the two outer contacts. Each time the lever touches one contact, the corresponding light bulb should turn on. This shows the switch directing electricity to one of the two circuits.

Helpful Tips

• An SPDT switch has one input and two possible outputs.
• The switch directs current to one output at a time.
• One position completes the first circuit.
• The other position completes the second circuit.
• Two light bulbs are often used to demonstrate operation.
• Only one bulb should be on at a time.
• The center connection is called the common terminal.
• The outer connections are the switched outputs.
• This type of switch is used in many electrical devices.
• Check for solid electrical contact at each position.

Requirement 10e: Three-Way Switch Wiring

What You Need To Do

Explain how a three-way switch circuit allows one light to be controlled from two different locations.

How a 3-Way Switch Circuit Works:
A 3-way lighting circuit uses two switches and one light. The switches are connected by three wires: a common wire and two traveler wires.

• Common Wire: This wire carries power from the electrical source or delivers power to the light.
• Traveler Wires: These two wires connect the switches and allow the flow of electricity to change paths, depending on the switch positions.

Steps in the Circuit:

1. Power enters the first switch through the common terminal.
2. Depending on the switch position, electricity flows through one of the two traveler wires to the second switch.
3. The second switch directs the electricity to the light or breaks the circuit to turn it off.

Helpful Tips

• A three-way circuit uses two switches and one light.
• Each switch has a common terminal.
• Two traveler wires connect the switches.
• Power enters one switch through its common terminal.
• The traveler wires provide alternate paths for current.
• The second switch either completes or interrupts the circuit.
• Either switch can change the state of the light.
• Three-way switches are often used on stairways and in hallways.
• The light can be turned on or off from either location.
• This wiring arrangement improves convenience in larger areas.

Leader Tips

• Use a wiring diagram to show the current path.
• Identify the common and traveler wires clearly.
• Relate the circuit to examples in homes or meeting places.
• Focus on the switching action rather than advanced wiring details.

Requirement 10f: Series And Parallel Circuits

What You Need To Do

Build a circuit with two lights connected in series and then rebuild it in parallel. Compare how the circuits operate.

Building a Series Circuit:

• Connect one terminal of the battery to one terminal of the first light.
• Connect the other terminal of the first light to one terminal of the second light.
• Connect the remaining terminal of the second light to the switch, and then back to the battery.
• When the switch is closed, electricity flows through both lights in sequence.

Building a Parallel Circuit:

• Connect one terminal of the battery to one terminal of both lights.
• Connect the other terminals of both lights to the switch, and then back to the battery.
• Each light has its own path for electricity to flow.

Differences Between Series and Parallel Circuits:

• Brightness: In a series circuit, the lights share the same current, so they will be dimmer. In a parallel circuit, each light receives full current, making them brighter.
• Failure: In a series circuit, if one light goes out, the circuit is broken, and both lights turn off. In a parallel circuit, if one light goes out, the other stays on because it has its own path.
• Current Flow: A series circuit has one path for electricity, while a parallel circuit has multiple paths, allowing current to flow independently to each light.

Helpful Tips

• A series circuit has only one path for current.
• A parallel circuit has multiple paths for current.
• Series-connected lights are usually dimmer.
• Parallel-connected lights are usually brighter.
• If one light fails in a series circuit, both lights go out.
• If one light fails in a parallel circuit, the other light stays on.
• Current flows through each light one after another in a series circuit.
• Each light receives its own path in a parallel circuit.
• Most household wiring uses parallel circuits.
• Compare brightness and operation before discussing the results.

Resources

• What Is the Difference Between Series and Parallel Circuits (video)

Leader Tips

• Have Scouts build both circuits themselves.
• Encourage careful observation of the differences.
• Discuss why homes use parallel wiring.
• Review the advantages and disadvantages of each design.
