Question

If Q is the electric charge which flows through a conductor in the time 't' such that 'I' is the magnitude of current, what is the relation between Q, t and I?

Answer 1

The mathematical relation between electric charge (Q), time (t), and current (I) is:

Q = I × t

Alternatively, it can be written as:

\[I = \frac{Q}{t}\]

(Electric current is the rate of flow of electric charge)

\[t = \frac{Q}{I}\]

Where:

Q = Electric charge (measured in coulombs, C)

I = Electric current (measured in amperes, A)

t = Time (measured in seconds, s)
