current=charge/time.so q=it,(300×10^-3)×2×60as 1 min =60 sec..after solving.q=36C..as charge on electron is equal to 1.6×10^-19C..so total no of electrons will b 36/1.6×10^-19=22.5×10^19 or 2.25×10^20

current=charge/time
charge=no of electrons*-1.67*10^-19(charge of one electron)(neglet minus since electrons are negatively charged)
therefore current=no of electrons*67*10^-19/time
=501^16 electrons
charge=no of electrons*-1.67*10^-19(charge of one electron)(neglet minus since electrons are negatively charged)
therefore current=no of electrons*67*10^-19/time
=501^16 electrons
please mark as the best if right
