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

When is an electric current produced? Explain.

Define $1 \ Coulomb$ in terms of $1 \ Ampere$.

Due to what is current formed in an electrolyte?

$A$ current of $4.8\,A$ is flowing through a conductor. The number of electrons flowing per second is:

$A$ source of $e.m.f.$ $E = 15\,V$ and having negligible internal resistance is connected to a variable resistance so that the current in the circuit increases with time as $i = 1.2t + 3$. Then,the total charge that will flow in the first five seconds will be ............... $C$.
