Formulas & Step-by-Step

Resistance

R = V ÷ I

120 ÷ 1,380.69 = 0.0869 Ω

Power

P = V × I

120 × 1,380.69 = 165,682.8 W

Verification (alternative formulas)

P = I² × R

1,380.69² × 0.0869 = 1,906,304.88 × 0.0869 = 165,682.8 W ✓

P = V² ÷ R

120² ÷ 0.0869 = 14,400 ÷ 0.0869 = 165,682.8 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 165,682.8 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.
