Question

You have been given the value of an electric charge $q$ flowing through a conductor in time $t$ seconds. Which relation below will you use to find out the amount of current $I$ flowing through the conductor.

• A. $I=\frac{q}{t}$
• B. $I=q\times t$
• C. $I=\frac{t}{q}$
• D. $I=\frac{I}{t^2}$

Answer 1

The correct option is A

$I=\frac{q}{t}$

If a charge $q$, flows across any cross-section of a conductor in time $t$, then the current $I$, through the cross-section is given by
$I=\frac{q}{t}$
