Quantisation of charge | Electrostatics | Siyavula

Unit of charge (ESAEY) The charge on a single electron is q e = 1,6 × 10 − 19 C. All other charges in the universe consist of an integer multiple of this charge. This is known as charge quantisation. Q = n q e. Charge is measured in units called coulombs (C). A coulomb of charge is a very large charge. In electrostatics we therefore often ...
