## No Load Voltage Formula

The following formula is used to calculate the No Load Voltage.

Vn = Vf + (Vf*LR/100)

- Where Vn is the No Load Voltage (volts)
- Vf is the full load voltage (volts)
- LR is the load regulation (%)

To calculate the no-load voltage, multiply the full-load voltage by the load regulation, then add the full-load voltage to this result.

## How to Calculate No Load Voltage?

The following two example problems outline how to calculate the No Load Voltage.

**Example Problem #1:**

- First, determine the full load voltage (volts). In this example, the full load voltage (volts) is measured to be 400.
- Next, determine the load regulation (%). For this problem, the load regulation (%) is calculated to be 15.
- Finally, calculate the No Load Voltage using the formula above:

Vn = Vf + (Vf*LR/100)

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

Vn = 400 + (400*15/100) = 460 (volts)

**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:

full load voltage (volts) = 300

load regulation (%) = 16

Entering these values into the formula above gives :

Vn = 300+ (300*16/100) = 348 (volts)
