What is the order of current flowing in the nerves of our body?

The electric current in a wire varies with time as $i = (2 + 3t) \text{ A}$. Calculate the charge that passes through the cross-section of the wire in $10 \text{ s}$.

The electric current through a wire varies with time as $I = I_0 + \beta t$,where $I_0 = 20 \ A$ and $\beta = 3 \ A/s$. The amount of electric charge that crosses through a section of the wire in $20 \ s$ is: (in $C$)

$A$ current through a wire depends on time as $i = \alpha_{0} t + \beta t^{2}$ where $\alpha_{0} = 20 \, A/s$ and $\beta = 8 \, As^{-2}$. Find the charge crossed through a section of the wire in $15 \, s$ (in $C$).

Electric current has both magnitude and direction. It is a

In conductors,in the absence of an electric field,although electrons are in motion,why is no current formed?
