## Total Current Formula

The following formula is used to calculate the Total Current.

IT = VT/RT

- Where IT is the Total Current (amps)
- VT is the total resistance (ohms)
- RT is the total voltage (volts)

To calculate total current, divide the total resistance and by the total voltage.

## How to Calculate Total Current?

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

**Example Problem #1:**

- First, determine the total resistance (ohms). In this example, the total resistance (ohms) is measured to be 500.
- Next, determine the total voltage (volts). For this problem, the total voltage (volts) is calculated to be 12.
- Finally, calculate the Total Current using the formula above:

IT = VT/RT

Inserting the values from above and solving the equation with the imputed values gives:

IT = 12/500 = .024 (amps)

**Example Problem #2: **

Using the same process as example problem 1, we first define the variables outlined by the formula. In this case, the values are:

total resistance (ohms) = 600

total voltage (volts) = 15

Entering these values into the formula above gives :

IT = 15/600 = .025 (amps)
