Electric current has both magnitude and direction. It is a

$A$ flow of $10^{7}$ electrons per second in a conducting wire constitutes a current of

The charge flowing in a conductor changes with time as $Q(t) = \alpha t - \beta t^2 + \gamma t^3$. Where $\alpha, \beta$,and $\gamma$ are constants. The minimum value of current is:

$5 \, A$ of current is passed through a metallic conductor. The charge flowing in one minute in coulombs will be:

The charge of an electron is $1.6 \times 10^{-19} \ C$. How many electrons strike the screen of a cathode ray tube each second when the beam current is $16 \ mA$?

$A$ steady current flows in a metallic conductor of non-uniform cross-section. The quantity/quantities constant along the length of the conductor is/are:
