Formulas & Step-by-Step

Resistance

R = V ÷ I

120 ÷ 597.33 = 0.2009 Ω

Power

P = V × I

120 × 597.33 = 71,679.6 W

Verification (alternative formulas)

P = I² × R

597.33² × 0.2009 = 356,803.13 × 0.2009 = 71,679.6 W

P = V² ÷ R

120² ÷ 0.2009 = 14,400 ÷ 0.2009 = 71,679.6 W

Circuit Analysis

Heat Dissipation

This circuit dissipates 71,679.6 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.

Frequently Asked Questions

R = V ÷ I = 120 ÷ 597.33 = 0.2009 ohms.
At the same 120V, current doubles to 1,194.66A and power quadruples to 143,359.2W. Lower resistance means more current, which means more power dissipated as heat.
V=IR, V=P/I, V=√(PR) | I=V/R, I=P/V, I=√(P/R) | R=V/I, R=V²/P, R=P/I² | P=VI, P=I²R, P=V²/R.
All 71,679.6W 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.
