Millikan demonstrated the quantisation of charge experimentally. Charge on electron =−e=−1.6× 100−19C. Addition of charge can occur in integral multiples of e.

Millikan demonstrated the quantisation of charge experimentally. Charge on electron $= - e = - 1.6 \times$ $10 0^{- 19} C$ . Addition of charge can occur in integral multiples of $e$ .
