Question

A current of 1.6mA flow through a conductor .If charge on an electon is -1.6*10^-19 Coulomb.find the number of electrons that will pass each second through the cross section of that conductor?

Answer 1

q =ne ( q= charge ; n= no. of elec. ; e= charge of elec. )
q= iT ( i = current ; t=time)
so ..ne=it

put the values and get ur ans.
