Answer:
Explanation:
Charge, Q = 1200 C
Number of electrons,
Explanation:
It is given that,
Current, I = 10 A
Time, t = 2 min = 120 s
(i) Let Q is the amount of charge passed through unit area of cross section of the conductor. It is given by :
Q = 1200 Coulomb
(ii) Charge of an electron,
Let n is the total number of electrons. It is given by using quantization of electric charge as :
