A conductor carries a current of 0.2A. Find the amount of charge that will pass through the cross-section of the conduction in 30 s. How many electrons will flow in this time interval? (Charge on an electron, e = 1.6 × 10−19 C)
Amount of charge = 0.2 × 30s = 6C
Number of electrons = 0.61.6×10−19 = 37.5 × 1017
