Front

What is a complete circuit?

Back

A complete circuit is a closed loop that allows electric current to flow, enabling devices like light bulbs to function.

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 light up.

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 switch in an electric circuit?

Back

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

Front

What is a series circuit?

Back

A series circuit is a type of circuit where components are connected end-to-end, so the same current flows through all components.

Front

What is a parallel circuit?

Back

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

Front

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

Back

If one bulb in a series circuit burns out, the circuit becomes incomplete, and all bulbs will go out.

Front

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

Back

If one bulb in a parallel circuit burns out, the other bulbs will remain lit because they have separate paths for current.

Front

What is the function of wires in a circuit?

Back

Wires connect the components of a circuit and allow electric current to flow between them.

Front

What is resistance in an electric circuit?

Back

Resistance is a measure of how much a material opposes the flow of electric current, affecting how much current flows in the circuit.
