Enter the total number of electrons and the electron charge (C) into the calculator to determine the Total Charge.

## Total Charge Formula

The following formula is used to calculate the Total Charge.

**Qtotal = N * e**

- Where Qtotal is the Total Charge (Coulombs)
- N is the total number of electrons
- e is the electron charge (C) (1.6 * 10 ^-19)

## How to Calculate Total Charge?

The following two example problems outline how to calculate the Total Charge.

**Example Problem #1:**

- First, determine the total number of electrons. In this example, the total number of electrons is given as 15,000.
- Next, determine the electron charge (C). For this problem, the electron charge (C) is given as 1.6 * 10 ^-19 C.
- Finally, calculate the Total Charge using the equation above:

Qtotal = N * e

Inserting the values from above and solving the equation:

Qtotal = 15000 * 1.6 * 10 ^-19 = 2.4 e-15 (Coulombs)

**Example Problem #2: **

Using the same process as above, first define the variables required by the formula. In this case, these values are provided as the following:

total number of electrons = 200,000

electron charge (C) = 1.6 * 10 ^-19 C

Entering these values gives:

Qtotal = N * e = 3.2e-14 (Coulombs)
