Enter the total excess charge and the charge of the electron into the calculator to determine the number of excess electrons.

Excess Electrons Formula

The following formula is used to calculate the number of Excess Electrons.

EE = EC / ELC

  • Where EE is the number of Excess Electrons
  • EC is the excess charge
  • ELC is the electron charge (1.60*10^-19 C)

To calculate the Excess Electrons, divide the excess charge by the charge of one electron.

What are Excess Electrons?

Definition:

Excess Electrons are a measure of the number of electrons in excess of a normal amount carried within a charge.

How to Calculate Excess Electrons?

Example Problem:

The following example outlines the steps and information required to calculate Excess Electrons.

First, determine the total excess charge. In this example, the total excess charge is 2*10^-18.

Next, determine the charge of one electron. This is known to be 1.60*10^-19 Coulombs.

Finally, calculate the number of Excess Electrons using the formula above:

EE = EC / ELC

EE = 2*10^-18 / 1.60*10^-19

EE = 12.5
