Question

how many electrons pass through a lamp in 1 min if the current is 220 miliampere

Answer 1

one sphere is the current that flows through a lamp when one coulomb of charge passes in one second. The charge of the electron is 1.602*10*19c . The number of electron that passes through a lamp in one second is equal to the number of electron that passes through a lamp in one minute.

Answer 2

I=q/t and q=ne where e = charge on each electron and n = number of electrons
