Answer» Answer: 2) 6.25x10^15 Explanation: 1ma= 1000 x 1 A =1000 A When 1000 COULOMB charge flow through a wire in 1 second then the current through the wire is 1000 AMPERE. I=Q/t 1 Ampere = 1 Coulomb /1 Second Charge on 1 ELECTRON = 1.6 x 10^-19 Coulomb By unitary method, If 1.6 x 10^-19 Coulomb / Second (Ampere) = Current by 1 electron then, 1( Coulomb / Second) or (Ampere) = 1000 / (1.6 x 10^-19) electrons i.e, 6.25 x 10^15 electrons.
