## 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
