Solution

If Q is the charge (in coulombs) flowing through a conductor in time t (in seconds) such that current I flows through the conductor then
Rate of flow of charge = `"Q"/"t"`
We know the rate of flow of charge = I = Electric current.
⇒ I = `"Q"/"t"` 

Concept: Types of Circuits: Simple Circuit
