Q

A device used to measure electric current.

25
the amount of charge (electrons) passing a certain point in a circuit each second. It is measured in amperes (A) using an ammeter
electric current
26
the flow of electrons through a conducting material. It is measured in amperes (A) and refers to the number of electrons that move through a wire per second.
current electricity
27
A continuous (unbroken) loop of conducting material through which electrons can move.
electric circuit
28
conductors that can open or close. They give control over the flow of electrons.
