What is a circuit?

Back

A circuit is a closed path through which electric current flows, consisting of a power source, conductors, and a load.

Front

What materials are needed to create a complete circuit?

Back

A complete circuit requires a power source (like a battery), conductors (like copper wire), and a load (like a light bulb).

Front

What is an insulator?

Back

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

Front

What is a conductor?

Back

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

Front

What happens if a circuit is incomplete?

Back

If a circuit is incomplete, the electric current cannot flow, and devices like light bulbs will not work.

Front

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to push the current through the circuit.

Front

What does it mean to close a switch in a circuit?

Back

Closing a switch completes the circuit, allowing electric current to flow and power devices.

Front

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

Back

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

Front

What can cause a circuit to stop working?

Back

A circuit can stop working if there is a break in the path, a dead battery, or a broken component like a light bulb.

Front

What is a series circuit?

Back

A series circuit is a type of circuit where components are connected one after another, so the same current flows through all components.
