Formulas & Step-by-Step

Resistance

R = V ÷ I

24 ÷ 662.15 = 0.0362 Ω

Power

P = V × I

24 × 662.15 = 15,891.6 W

Verification (alternative formulas)

P = I² × R

662.15² × 0.0362 = 438,442.62 × 0.0362 = 15,891.6 W ✓

P = V² ÷ R

24² ÷ 0.0362 = 576 ÷ 0.0362 = 15,891.6 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 15,891.6 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.
