Power Output Calculator
Calculate electrical power output in watts, kilowatts, and horsepower. Determine power from voltage, current, resistance, or work and time using multiple calculation methods.
Step 1: Electrical Parameters
Power Calculation Formulas
Power (P) = Voltage (V) × Current (I)
Also: P = I² × R or P = V² / R
Mechanical: P = Work (W) / Time (t)
Step 2: System Settings
About Power Calculations
For AC systems, real power = V × I × PF. Power factor accounts for phase difference between voltage and current. Efficiency reduces actual output power.

Power Calculation Breakdown
Power Calculation Formulas
P = V × I × PF (for AC) or P = V × I (for DC)
Where: V = Voltage, I = Current, PF = Power Factor
For mechanical power: P = Work / Time
Considering efficiency: Output Power = Calculated Power × Efficiency
