electric current

The charge flowing through a conductor beginning with time $t=0$ is given by the formula $q=2t^2+3t+1\left(\mathrm{Couloms}\right)$.Find the current $i=\frac{dq}{dt}$ at the end of $5^{\mathrm{th}}$ second.

An electron is revolving in a circle of radius $r$ with angular speed $\omega$. Find current and its direction.

Does current depend on resistance?

The current through an element is shown in the figure. Determine the total charge that passes through the element after  $t= 2 \mathrm{s}$ in Coulombs.

The current through an element is shown in the figure. Determine the total charge that has passed through the element at $t=0 \mathrm{s}$ in Coulombs.

A current in a wire is given by the equation, $\mathrm{I}=2 t^2-3 t+1$, the charge through cross section of wire in time interval $\mathrm{t}=3\mathrm{ }\mathrm{s}$ to $t=5\mathrm{ }\mathrm{s}$ is _____$.34 \mathrm{C}$.
