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, through conductors, and back to the power source.

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily, such as metals like copper and aluminum.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily, such as rubber, wood, or plastic.

Front

What happens if a circuit is incomplete?

Back

If a circuit is incomplete, electricity cannot flow, and devices connected to the circuit will not work.

Front

What is a series circuit?

Back

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

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

Back

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

Front

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

Back

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

Front

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to push the current through the circuit.

Front

What is a switch in an electrical circuit?

Back

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