Question

Explain quantisation of charge.

✓

Answer

►Experimentally it is established that all fret charges are integral multiples of a basic unit of charge denoted by $e$. Thus charge $q$ on a body is always given by $q=n e$.
►where $n$ is any integer. This basic unit of charge is the charge that an electron or proton carries. By convention, the charge on an electron is taken to be negative; therefore charge on an electron is written as $-e$ and that on a proton as $+e$.
►The quantisation of charge was first suggested by the experimental laws of electrolysis discovered by english experimentalist Faraday.
