## No Load Voltage Calculator

Enter the values of full load voltage, V_{f(V)} and load regulation, LR to determine the value of No load voltage, V_{n(V)}.

__No Load Voltage Formula:__

No Load Voltage is a key concept in electrical and electronic engineering, particularly relevant to transformers, generators, and power supplies.

It refers to the voltage measured across the output terminals of a device when no load is connected.

No Load Voltage is typically higher than the voltage under load conditions due to the absence of voltage drop across the internal impedance.

Understanding and calculating No Load Voltage is essential for designing and testing electrical devices to ensure they operate correctly in various scenarios.

No load voltage, V_{n(V)} in volts equals the full load voltage, V_{f(V)} in volts plus the product of the full load voltage, V_{f(V)} in volts and the load regulation, LR in percentage divided by one hundred.

No load voltage, V_{n(V)} = V_{f(V)} + (V_{f(V)} * LR) / 100

V_{n(V)} = no load voltage in volts, V.

V_{f(V)} = full load voltage in volts, V.

LR = load regulation.

__No Load Voltage Calculation:__

- Determine the no load voltage if the full load voltage is 110 volts and the load regulation is 2%:

Given: V_{f(V)} = 110V, LR = 2%.

No load voltage, V_{n(V)} = V_{f(V)} + (V_{f(V)} * LR) / 100

V_{n(V)} = 110 + (110 * 2) / 100

V_{n(V)} = 110 + 2.2

V_{n(V)} = 112.2V.

- Suppose you have a no load voltage of 115 volts, and a full load voltage of 110 volts. Using these values, find the load regulation percentage:

Given: V_{f(V)} = 110V, V_{n(V)} = 115V.

No load voltage, V_{n(V)} = V_{f(V)} + (V_{f(V)} * LR) / 100

LR = 100 * (V_{n(V)} – V_{f(V)}) / V_{f(V)}

LR = 100 * (115 – 110) / 110

LR = 100 * 5 / 110

LR = 4.545%.
