Answer:
An electric current is the rate of flow. of electric charge past a point or a region. an electric current is said to exist when there is net flow of electric charge through a region 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 .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.
