RMS & Power Reference
RMS = Root Mean Square
P = V²/R (Voltage & Resistance)
P = I²R (Current & Resistance)
P = VI cos φ (AC Power)
Household AC = 120V/240V RMS
European AC = 230V RMS
Industrial 3φ = 480V RMS
RMS = Peak ÷ √2
Apparent Power = VI (VA)
Real Power = VI cos φ (W)
Reactive Power = VI sin φ (VAR)
Power Factor = cos φ
