Circuits

A circuit is a closed path through which electricity flows.

An electrical current is the flow of electric charge through a circuit.

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

A conductor is a material that allows electricity to flow through it easily, like copper or aluminum.

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

When a circuit is incomplete, electricity cannot flow, and devices like light bulbs will not work.

A battery is a device that stores electrical energy and provides power to a circuit.

A light bulb is a device that converts electrical energy into light energy.

A resistor is a component that limits the flow of electrical current in a circuit.

Connecting wires means joining them together to create a complete path for electricity to flow.
