Answer 2

To find the relation between electric current, I electric charge, Q and time, t we will use this analogy.

Consider a pipe through which water is flowing.

If the rate of flow of water through the pipe is, for example, 25litresmin-1, then in 15minutes, the total quantity of water which has moved through the pipe is obviously 25×15 = 375litres

Apply the same simple logic to the case of electric current:

A current of I Amps means that I Coulombs of charge flow per second.

Therefore in time t the total charge which has passed any point through which the current flows will (again, obviously!) be I×t

Therefore, the relation we are looking for is

and this equation can now be used to define the Coulomb

1C is the quantity of charge which flows past any point in a circuit in which a current of 1A flows for for 1s

This, of course, assumes we have already defined precisely what we mean by a current of 1A
