It is a flow of current through a material.

These are materials through which electrons cannot freely move or do not easily flow.

It is a closed-loop consist of a power source, wires, a load, and a switch.

These are metallic materials used to connect an electrical appliance to a source of electricity.

A type of switch that automatically turns off the circuit when the current that flows through it becomes too large.

It is used to increase the voltage of the electric current.

It is consists of filament, a bulb, and a base.

It is a safety device consisting of a strip of metal with a low melting point.

An electric current will flow only when all the parts are connected. This means that the circuit is ________.

It is the accumulation of electric charges on the surface of objects. This phenomenon is usually caused by friction. It is called ____________.
