The current in the conductor is 0.2A. What is the electric charge and how many electrons pass through its cross section in 2 minutes?
I = 0.2 A.
t = 2 min = 120 s.
q = 1.6 * 10 ^ -19 Cl.
Q -?
N -?
I = Q / t.
Q = I * t.
Q = 0.2 A * 120 s = 24 Cl.
Q = q * N.
N = Q / q.
N = 24 C / 1.6 * 10 ^ -19 C = 15 * 10 ^ 19.
Answer: an electric charge Q = 24 C passes through the cross-section of the conductor, N = 15 * 10 ^ 19 electrons pass.
