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 components like wires and devices, and back to the power source.

What is the purpose of insulation on electrical wires?

Back

Insulation on electrical wires is used to make it safe by preventing electricity from escaping the wire and causing shocks or fires.

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, plastic, or wood.

Front

What happens in a closed circuit?

Back

In a closed circuit, electricity flows freely, allowing devices like light bulbs to turn on.

Front

What happens in an open circuit?

Back

In an open circuit, the flow of electricity is interrupted, preventing devices from turning on.

Front

What is a battery's role in a circuit?

Back

A battery provides the electrical energy needed to power 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.

Front

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

Back

A light bulb converts electrical energy into light energy when electricity flows through it.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of circuit where there are multiple paths for electricity to flow, so if one path is broken, others can still work.
