## Electronic PowerP = Power in WattsV = Electrical potential, Volts I = Current, Amperes R = Resistance, Ohms Ohms Law: V = IR Example: V=120V and R=8 Ohms I = V/R, I = 120V/8 Ohms I = 15A (circuit requires 15A) P = I^2 R Example: P=15A^2 * 8 Ohms = 1800W P = VI Example: P = (120V)(15A) = 1800W Energy usage (power x time) P = (600W)(1 kW/1000W) = 0.6 kW Energy in kWh: E = (0.6kW)(10h) = 6 kWh |
