Formulas & Step-by-Step

Resistance

R = V ÷ I

208 ÷ 267.29 = 0.7782 Ω

Power

P = V × I

208 × 267.29 = 55,596.32 W

Verification (alternative formulas)

P = I² × R

267.29² × 0.7782 = 71,443.94 × 0.7782 = 55,596.32 W

P = V² ÷ R

208² ÷ 0.7782 = 43,264 ÷ 0.7782 = 55,596.32 W

Circuit Analysis

Heat Dissipation

This circuit dissipates 55,596.32 watts of power as heat. In a resistor, all electrical energy at steady state converts to thermal energy. The actual component power rating needs headroom above this steady-state figure, but the specific derating depends on resistor type (carbon-comp, metal-film, wirewound each behave differently), ambient temperature, airflow or heat-sinking, and whether the load is continuous or pulsed. Check the resistor datasheet for the manufacturer-specific derating curve rather than applying a blanket margin.

All 55,596.32W is dissipated as heat in a pure resistor at steady state. The component power rating needs headroom above this steady-state figure, but the specific derating depends on resistor type (carbon-comp, metal-film, wirewound each behave differently), ambient temperature, airflow or heat-sinking, and whether the load is continuous or pulsed. Check the resistor datasheet for the manufacturer-specific derating curve.
For purely resistive loads, yes. For reactive loads, use impedance (Z) instead of resistance (R). Z includes both resistance and reactance, and the V/I phase shift shows up in power factor.
P = V × I = 208 × 267.29 = 55,596.32 watts.
