Question

State the relation between current (I) passing in conductor, number of electrons(n), flowing through cross section of conductor magnitude of charge on an electron(e) and time (t).

Answer 1

Answer:

I = Q/t

I - current flowing, Q - charge, t - time

Q = n*e (e as here these are electons)

n = 6.25*(10^18) e = 1.6*(10^-19)

Q = {6.25*(10^18)} * {1.6*(10^-19)}

Q = 1 C

t = 5*60 = 300 sec

I = 1/300 = 3.33*(10^-3) A

I = 3.33 mA
