Front

What is a circuit?

Back

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

Front

What are the main components of a simple electric circuit?

Back

The main components are a power source (like a battery), conductors (wires), and a load (like a light bulb).

Front

What happens when a circuit is complete?

Back

When a circuit is complete, electricity can flow, and devices like light bulbs will turn on.

Front

What is a fuse in an electric circuit?

Back

A fuse is a safety device that protects the circuit by breaking the connection if the current is too high.

Front

What is the role of a switch in a circuit?

Back

A switch controls the flow of electricity by opening (off) or closing (on) the circuit.

Front

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

Back

In a series circuit, all components are connected in a single path, while in a parallel circuit, components are connected across common points, allowing multiple paths for current.

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 will continue to light up.

Front

What is the purpose of the metal posts on a battery?

Back

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

Front

What is electric current?

Back

Electric current is the flow of electric charge, typically measured in amperes (A).
