How the formula works
P = V × I | P_AC = V × I × PF | S = V × I | R = V ÷ I
- DC Power (P) = Voltage × Current (Watts)
- AC Real Power (P) = Voltage × Current × Power Factor (Watts)
- AC Apparent Power (S) = Voltage × Current (VA)
- Reactive Power (Q) = √(S² − P²) (VAR)
- Resistance (R) = Voltage ÷ Current (Ohms)
- Power Factor (PF) = Real Power ÷ Apparent Power
- Ohm's Law: V = I × R, I = V ÷ R, R = V ÷ I
