Formulas & Step-by-Step

Resistance

R = V ÷ I

24 ÷ 243.91 = 0.0984 Ω

Power

P = V × I

24 × 243.91 = 5,853.84 W

Verification (alternative formulas)

P = I² × R

243.91² × 0.0984 = 59,492.09 × 0.0984 = 5,853.84 W ✓

P = V² ÷ R

24² ÷ 0.0984 = 576 ÷ 0.0984 = 5,853.84 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 5,853.84 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.
