Enter the volt-amps (VA) and the total voltage (volts) into the calculator to determine the 3 Phase Current.

**Calculator Operations:**

- Solve for 3 phase current given volt-amps and volts.
- Solve for volt-amps given 3phase current, and volts.
- Solve for volts given 3 phase current and volt-amps.

## 3 Phase Current Formula

The following formula is used to calculate the 3 Phase Current.

**I3 = VA/ V**

- Where I3 is the 3 Phase Current (amps)
- VA is the volt-amps (VA)
- V is the total voltage (volts)

## How to Calculate 3 Phase Current?

The following two example problems outline how to calculate the 3 Phase Current.

**Example Problem #1:**

- First, determine the volt-amps (VA). In this example, the volt-amps (VA) is measured to be 45.
- Next, determine the total voltage (volts). For this problem, the total voltage (volts) is calculated to be 5.
- Finally, calculate the 3 Phase Current using the formula above:

I3 = VA/ V

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

I3 = 45/ 5 = 9 (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:

volt-amps (VA) = 75

total voltage (volts) = 6

Entering these values into the formula above gives :

I3 = 75/ 6 = 12.5 (amps)
