Unless specified, this website is not in any way affiliated with any of the institutions featured. All other charges in the universe consist of an integer multiple of this charge. Before the spheres touch, the total charge is: \(-\text{5}\text{ nC} + (-\text{3}\text{ nC}) = -\text{8}\text{ nC}\). Physics » Electric Charges and Fields » Quantization Of Charge. Unit of Electric Charge There are many properties of electricity which are all expressed using different units of measurement. In 1909 Robert Millikan and Harvey Fletcher measured the charge on an electron.
Units of charge are Coulombs and Ampere–second. Millikan and Fletcher sprayed oil droplets into the space between two charged plates and used what they knew about forces and in particular the electric force to determine the charge on an electron.
I then bring the spheres together so that they touch each other. I have \(\text{2}\) charged metal conducting spheres on insulating stands which are identical except for having different charge. The charge on a single electron is \({q}_{e} = \text{1.6} \times \text{10}^{-\text{19}}\text{ C}\).All other charges in the universe consist of an integer multiple of this charge.

Sphere A has a charge of \(\text{5}\) \(\text{nC}\) and sphere B has a charge of \(-\text{3}\) \(\text{nC}\). How many excess electrons does it have? The basic unit of charge, called the elementary charge, e, is the amount of charge carried by one electron.
