Question

Millikan measured the quantity of charge carried

by an electron. How did he then calculate the
mass of an electron?

Answer 1

m = E × Q

And Q = I × t

m = E × I × t

Where m = mass in grams

Q = quantity of electricity in coulomb

I = current in ampere

t = time in seconds

E = electrochemical equivalent of the substance
