Estimate the magnitude of current that passes through a wire, if $0.1 \text{ mol}$ of electrons flow through it in $40 \text{ min}$. (Assume Avogadro number $= 6 \times 10^{23}$) (in $\text{ A}$)

$A$ current of $1\, mA$ is flowing through a copper wire. How many electrons will pass a given point in one second?

The following figure shows four situations in which positive and negative charges move horizontally through a region and gives the rate at which each charge moves. Rank the situations according to the effective current through the region,greatest first.

The electric current flowing through a given conductor varies with time as shown in the graph below. The number of free electrons which flow through a given cross-section of the conductor in the time interval $0 \leq t \leq 20 \ s$ is

“In lightning in the sky,there is a steady flow of charge”. -True or False?

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