Tap Voltage Calculator

Formula

The formula to calculate the Tap Voltage (Vt) is:

$Vt = Vs \times \frac{T}{100}$

Where:

Tap Voltage: The voltage obtained by adjusting the tap on a transformer, calculated by multiplying the tap up percentage by the secondary voltage.
Significance: Used in electrical engineering to adjust the voltage levels in transformers for various applications.

Let's say the secondary voltage (Vs) is 240 volts and the tap up percentage (T) is 5%. Using the formula:

$Vt = 240 \times \frac{5}{100} = 12$

So, the tap voltage (Vt) is 12 volts.
