Who discovered charge of electron ? State charge mass of electron.

Explanation

R.A Millikan devised oil drop experiment to determine the charge on the electrons.
According to Millikan the charge of the electron `=- 1.6 xx 10^(19) C`
The present accepted value of electrical charge is `=- 1.6022 xx 10^(19) C`
Mass of electron =`m_(e )`
`= (e)/( e//m_(e )) = (1.6022 xx 10^(19) C ) /( 1.758820 xx 10^(11) C kg^(-1))`
