Most of the electricity you use daily consists of a flow of tiny, negatively charged particles called
Electrons
Electric current moves along a path called a
Conductor
Any electrical appliance activated by the flow on am electric current such as a facial steamer is known as a

Direction
All of the following terms are types of waveforms except
Round
When too many appliances are put on one circuit and are operated at the same time, more current flows than the line is designed to carry. This is known as
Overload
Fires in electrical circuits can occur if
Too many appliances use the same wall socket and overload the circuit
What can occur anytime a foreign conductor comes in contact with a wire carrying current to an appliance
