Question

A charge of 12 c passes through an electroplating apparatus in 2.0 min. what is the average current?

Answer 1

Answer:

Q = I t          Q due to current I in t seconds

I = Q / t = 12 C / 120 sec = .1 C/sec

Note that 1 C represents N * 1.60E-19 electrons of charge

or 1 C = 6.25E18 electrons = 6.25 billion billion electrons
