Power Factor to Voltage Calculator
Enter the values of power, W(W), power factor, PF and current, A(A) to determine the value of Voltage, V(V).
Power Factor to Voltage Formula:
Power factor to voltage conversion is an essential concept in electrical engineering, particularly concerning the efficiency and performance of AC (alternating current) electrical systems.
The power factor (PF) measures the efficiency with which electrical power is converted into useful work output.
Understanding this relationship is crucial for optimizing electrical system performance and reducing energy losses.
Voltage, V(V) in volts is calculated by dividing the power, W(W) in watts by the product of power factor, PF and current, A(A) in amperes.
Voltage, V(V) = W(W) / PF * A(A)
V(V) = voltage in volts, V.
W(W) = power in watts, W.
PF = power factor.
A(A) = current in amperes, A.
Power Factor to Voltage Calculation:
1. Calculate the voltage for a system with a real power of 500 watts, a power factor of 0.8, and a current of 2 amperes:
Given: W(W) = 500W, PF = 0.8, A(A) = 2A.
Voltage, V(V) = W(W) / PF * A(A)
V(V) = 500 / 0.8 * 2
V(V) = 500 / 1.6
V(V) = 312.5V.
2. Determine the current for a system with a real power of 1000 watts, a power factor of 0.9, and the voltage is 222.22V:
Given: W(W) = 1000W, PF = 0.9, A(A) = 2A.
Voltage, V(V) = W(W) / PF * A(A)
A(A) = W(W) / PF * V(V)
A(A) = 1000 / 0.9 * 2
A(A) = 1000 / 1.8
A(A) = 5A.
