What is a circuit?

Back

A circuit is a closed loop that allows electric current to flow, consisting of a power source, conductors, and a load.

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

Back

A light bulb converts electrical energy into light energy.

Front

What is the function of a switch in a circuit?

Back

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

Front

What happens if there is no energy source in a circuit?

Back

If there is no energy source, the circuit will not function, and no current will flow.

Front

What is the purpose of wires in a circuit?

Back

Wires carry electrical energy from the power source to the load (e.g., light bulb).

Front

What is a complete circuit?

Back

A complete circuit is one that has a continuous path for current to flow, including a power source, conductors, and a load.

Front

What is an open circuit?

Back

An open circuit is a broken path where current cannot flow, often due to a switch being off or a break in the wiring.

Front

What is a closed circuit?

Back

A closed circuit is a complete path that allows current to flow uninterrupted.

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, components are connected end-to-end, so current flows through each component. In a parallel circuit, components are connected across common points, allowing current to flow through multiple paths.

Front

What is resistance in a circuit?

Back

Resistance is a measure of the opposition to the flow of electric current, typically measured in ohms.
