Webb- GCSE SCIENCE. Electricity What is a Coulomb? A coulomb is a unit of electrical charge. Charge is given the symbol Q. Electrons are tiny and have a very small charge. In the physics of electricity, we take a very large number of electrons as 1 unit of charge called a coulomb. 1 coulomb = 6·2 x 10 18 electrons.
