What is the direction of electric current inside an electrolyte?

The electric current in a conductor varies with time $t$ as $I = 2t + 3t^2$,where $I$ is in amperes and $t$ is in seconds. Find the total charge $Q$ (in $C$) that passes through the cross-section of the conductor from $t = 2 \ s$ to $t = 3 \ s$.

How is current formed in conductors?

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

Number of electrons flowing per second in a conductor carrying a current of $9 \,A$ is

The current in a wire varies with time according to the relation $I = 4 + 2t$. The quantity of charge which has passed through a cross-section of the wire during the time $t = 2 \, s$ to $t = 6 \, s$ will be .............. $C$.
