Understanding Circuits and Conductors

Front

What is a circuit?

Back

A circuit is a closed loop that allows electricity to flow from a power source to a device and back again.

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 rubber or plastic.

Front

What is the function of a battery in a circuit?

Back

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

Front

What happens when a switch is closed?

Back

When a switch is closed, it completes the circuit, allowing electricity to flow.

Front

What happens when a switch is open?

Back

When a switch is open, it breaks the circuit, stopping the flow of electricity.

Front

What are the two ends of a battery called?

Back

The two ends of a battery are called positive and negative.

Front

Why is it important to use insulated wires in a circuit?

Back

Insulated wires prevent accidental contact with the electrical current, making the circuit safer.

Front

What is the role of a light bulb in a circuit?

Back

A light bulb converts electrical energy into light energy when electricity flows through it.

Front

What is a series circuit?

Back

A series circuit is a circuit where all components are connected in a single path, so the same current flows through all of them.
