Front

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 (like a light bulb).

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, 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 is a switch in a circuit?

Back

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

Front

What does it mean for a light bulb to be part of a complete circuit?

Back

For a light bulb to work, it must be connected in a complete circuit, allowing current to flow through it.

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 is the difference between a series circuit and a parallel circuit?

Back

In a series circuit, components are connected one after another, while in a parallel circuit, components are connected across the same voltage source.
