Formulas & Step-by-Step

Resistance

R = V ÷ I

120 ÷ 696.3 = 0.1723 Ω

Power

P = V × I

120 × 696.3 = 83,556 W

Verification (alternative formulas)

P = I² × R

696.3² × 0.1723 = 484,833.69 × 0.1723 = 83,556 W ✓

P = V² ÷ R

120² ÷ 0.1723 = 14,400 ÷ 0.1723 = 83,556 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 83,556 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.
