Question

give an elementary discrimination of current flow through a conductor​

Answer 1

An electric current is the rate of flow of electric charge past a point[1]:2[2]:622 or region.[2]:614 An electric current is said to exist when there is a net flow of electric charge through a region.[3]:832 In electric circuits this charge is often carried by electrons moving through a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in an ionized gas (plasma).[4]

Electric current



A simple electric circuit, where current is represented by the letter i. The relationship between the voltage (V), resistance (R), and current (I) is V=IR; this is known as Ohm's law.
