Answer to Question #109549 in Electric Circuits for Izaaz Islam

Question

In what time would a current of 3A transfer a charge of 30C?

Answer 1

Explanation

• The relationship between electric charge, current & time is $i=\frac{dq}{dt}$ ; more simply $i= \frac{Q}{t}$

Calculation

Therefore, the time taken for the transfer,

$\qquad \begin{aligned} \small t&= \small \frac{Q}{i}\\ &=\small \frac{30C}{3A}\\ &=\small \bold{10s} \end{aligned}$
