Question

What is the quantum of electric charge?

Answer 1

1. According to the quantum nature of the charge, electric charge always occurs as an integral multiple of electronic charge (e).
2. That is, $Electriccharge,Q=\pm ne$.
3. Thus, the charge on a body is either$\pm e,\pm 2e,\pm 3e,\pm 4e.......$. and so on.
4. Where, Q = Electric charge and e = Electronic charge, and $n=l,2,3..........$.
5. The presently accepted value of an electronic charge is 1.6021 x 10-¹⁹ coulombs.
6. That is,$e=1.6021x10-19C$.
