Question

charge of electron was founded by______.​

Answer 1

J. J. Thomson

The experiment helped earn Millikan a Nobel prize in 1923 but has been a source of some controversy over the years. J. J. Thomson discovered the electron in 1897 when he measured the charge-to-mass ratio for electrons in a beam. But the value of the charge and whether it was fundamental remained open questions.

Answer 2

$\huge \colorbox{red}{❥Answer}$

• JJ Thomson is the undisputed discoverer of the electron. However, despite all those experiments he performed on it, he could only manage to obtain the electron's charge to mass ratio. The distinction of being the first to measure the electron's charge goes to Robert Millikan through his oil-drop experiment in 1909....
