A current of 5 m A is passing through a wire.how many electrons are passing per minute any cross section of the wire?

A conductor has 2.4*10 power-18 c charge. how many electrons are in excess or short?
What will be the value of current in a circuit if charge of 30 C is passing per minute through each point?

You need the duration of time the current passed through the wire to get the Coulombs, which you need to get the number of electrons any cross section of the wire per minute. When you have the time duration, check out how the calculations are done on www.monmsci.net/~fasano/phys2/Chap26_08.pdf.
