What is the charge on an electron?

R.A. Millikan devised a method known as the oil drop experiment. The charge on the electrons is determined using this experiment.

Charge on electron

• Electrons are negatively charged.
• The charge on an electron is $–1.6\times {10}^{–19}\text{C}$.
• The accepted value of the electrical charge is $–1.602176\times {10}^{–19}\text{C}$.
