Electric Circuits

Front

What is an electric circuit?

Back

An electric circuit is a closed loop that allows electricity to flow, consisting of a power source, conductors, and a load (like a light bulb).

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily, such as copper or aluminum.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily, such as wood or rubber.

Front

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to power the circuit.

Front

What happens when a circuit is open?

Back

When a circuit is open, the flow of electricity is interrupted, and devices like light bulbs do not work.

Front

What happens when a circuit is closed?

Back

When a circuit is closed, electricity can flow freely, allowing devices like light bulbs to work.

Front

What is a switch?

Back

A switch is a device that can open or close a circuit, controlling the flow of electricity.

Front

What is the best conductor of electricity among common materials?

Back

Copper is the best conductor of electricity among common materials.

Front

What is the purpose of wires in a circuit?

Back

Wires are used to connect different components of a circuit, allowing electricity to flow between them.

Front

What is a load in an electric circuit?

Back

A load is any device that uses electricity to perform work, such as a light bulb or motor.
