The relationship between charge (Q), current (I), and time (t) is as follows:

An electric current (I) is defined as a rate of flow of charged particles.

Current (I) = Amount of Charge (Q)/time taken (t)

I=Q/t

An extra piece of information:

- In the SI (Standard International) system of units, the amount of charge is measured in "Coulombs" and time in "seconds". Thus SI unit of current is Coulomb/second which is known as Ampere (A).
- In the metallic conductors, the charged particles are free electrons and the net flow of these electrons in one direction is known as electric current. Keep in mind, we need a source of energy, for example, a cell or battery, to make the free electrons move in the same direction.

Hi Marjolaine! The equation most commonly used is Q = It, where Q is the charge, I is the current and t is the time.

current is directly proportional to charge and inversely proportional to time. So, equation is I=Q/t
