Electricity and Circuits

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily. Examples include rubber and plastic.

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily. Examples include metals like copper and aluminum.

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.

Front

What is a series circuit?

Back

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

Front

What is a parallel circuit?

Back

A parallel circuit is a type of circuit where the components are connected across common points, allowing multiple paths for electricity to flow.

Front

Why is copper commonly used in electrical wiring?

Back

Copper is used in electrical wiring because it is an excellent conductor of electricity.

Front

What happens when a circuit is open?

Back

When a circuit is open, the flow of electricity is interrupted, and devices in the circuit will not work.

Front

What happens when a circuit is closed?

Back

When a circuit is closed, electricity can flow freely, and devices in the circuit will operate.

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 is a light bulb in a circuit?

Back

A light bulb is a device that converts electrical energy into light energy when electricity flows through it.
