Electrical Circuits

Front

What is an electrical circuit?

Back

An electrical circuit is a closed loop that allows electricity to flow from a power source to an output device, like a light bulb.

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical loop that allows electricity to flow.

Front

What is an open circuit?

Back

An open circuit is a broken electrical loop that does not allow electricity to flow.

What happens to a light bulb in a closed circuit?

Back

The light bulb will light up because the circuit is complete.

Front

What happens to a light bulb in an open circuit?

Back

The light bulb will not light up because the circuit is broken.

Front

What is a series circuit?

Back

A series circuit is a type of circuit where components are connected one after another, so the same current flows through all of them.

Front

What happens if one bulb in a series circuit is removed?

Back

If one bulb in a series circuit is removed, all bulbs will go out because the circuit is broken.

Front

What is the purpose of insulation on electrical wires?

Back

Insulation, usually made of plastic, is used to make electrical wiring safe by preventing accidental contact with the wire.

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 electricity to flow.

Front

What happens if one bulb in a parallel circuit is removed?

Back

If one bulb in a parallel circuit is removed, the other bulbs will remain lit because they have separate paths for electricity.
