Front

What is a circuit?

Back

A circuit is a closed path through which electric current flows.

Front

What are the two main components of a circuit?

Back

The two main components of a circuit are a power source (like a battery) and a load (like a light bulb or bell).

Front

What is the purpose of a switch in a circuit?

Back

A switch is used to open or close a circuit, allowing or stopping the flow of electricity.

Front

What happens when a circuit is complete?

Back

When a circuit is complete, electricity can flow, and devices like lights or bells will work.

Front

What is a battery?

Back

A battery is a device that stores electrical energy and provides power to a circuit.

Front

What is the role of metal posts on a battery?

Back

The metal posts on a battery connect to the circuit, allowing electricity to flow from the battery to the circuit.

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.

Front

What is a parallel circuit?

Back

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

Front

What happens if one light bulb burns out in a series circuit?

Back

If one light bulb burns out in a series circuit, the entire circuit is broken, and all bulbs will go out.

Front

What happens if one light bulb burns out in a parallel circuit?

Back

If one light bulb burns out in a parallel circuit, the other bulbs can still light up because they have separate paths for current.
