Fun with Circuits

What is a circuit?

• A circuit is a method of measuring voltage.

• A circuit is a closed loop that allows electric current to flow.

• A circuit is a device that stores energy.

• A circuit is a type of electrical appliance.

What do we call materials that allow electricity to flow?

• Insulators

• Conductors

• Resistors

• Semiconductors

What is an example of an insulator?

• Rubber

• Iron

• Aluminum

• Copper

How do you connect a battery in a circuit?

• Connect both terminals of the battery to the same side of the circuit.

• Connect the positive terminal to the negative side of the circuit and the negative terminal to the positive side.

• Connect the battery in parallel with the circuit components.

• Connect the positive terminal of the battery to the positive side of the circuit and the negative terminal to the negative side.

What happens when you turn on a circuit?

• The circuit becomes a resistor.

• The circuit generates heat only.

• The circuit emits light without current.

• Electrical current flows through the circuit.

What is the purpose of a switch in a circuit?

• To store electrical energy for later use.

• To increase the voltage in a circuit.

• To convert AC to DC in a circuit.

• To control the flow of electricity in a circuit.

What do you need to make a simple circuit?

• A power source, conductive material, and a load.

• A battery and a switch only

• A power source and a fuse

• Conductive material and a resistor only

Why is it important to use conductors in a circuit?

• Conductors are primarily used to store electric charge.

• Conductors are only necessary for high-voltage applications.

• It is important to use conductors in a circuit because they facilitate the flow of electric current, allowing the circuit to function properly.

• Conductors are used to insulate the circuit from external interference.
