Question

What is the relationship between Q(charge) I (current) t(time)?

Answer 1

I = Q/t
Electrical current is much like the current in a river. A current in a river grows if the amount of water passing in a given time increases.
Similarly for electrical current, it will increase if the amount charge passing a point in a given time changes.

Answer 2

flow of charge is current, and mathematically it is defined as the flow of charge per unit time

Answer 3

I = dQ/dt
