Understanding Power Calculations
Electrical power calculation involves several key formulas:
- Basic Power Formula: P = V × I (Power = Voltage × Current)
- With Resistance: P = V²/R or P = I² × R
- Real Power (AC Systems): P = V × I × PF (Power Factor)
- Three-Phase Power: P = √3 × V × I × PF
- Energy Consumption: E = P × t (Energy = Power × Time)
Practical Applications
