Formulas & Step-by-Step

Resistance

R = V ÷ I

208 ÷ 702.32 = 0.2962 Ω

Power

P = V × I

208 × 702.32 = 146,082.56 W

Verification (alternative formulas)

P = I² × R

702.32² × 0.2962 = 493,253.38 × 0.2962 = 146,082.56 W ✓

P = V² ÷ R

208² ÷ 0.2962 = 43,264 ÷ 0.2962 = 146,082.56 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 146,082.56 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.

Does Ohm's Law work for AC circuits?expand_more

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.

All 146,082.56W 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.
