Power Factor & Power Formulas

AC Power Formulas

Power Factor:PF = cos(φ)
True Power:P = V × I × PF
Apparent Power:S = V × I
Reactive Power:Q = V × I × sin(φ)

Power Triangle

Power Factor:PF = P ÷ S
True Power:P = √(S² - Q²)
Apparent Power:S = √(P² + Q²)
Reactive Power:Q = √(S² - P²)

P = True Power (Watts), S = Apparent Power (VA), Q = Reactive Power (VAR), PF = Power Factor (0-1)
