Formulas & Step-by-Step

Resistance

R = V ÷ I

24 ÷ 429.62 = 0.0559 Ω

Power

P = V × I

24 × 429.62 = 10,310.88 W

Verification (alternative formulas)

P = I² × R

429.62² × 0.0559 = 184,573.34 × 0.0559 = 10,310.88 W

P = V² ÷ R

24² ÷ 0.0559 = 576 ÷ 0.0559 = 10,310.88 W

Circuit Analysis

Heat Dissipation

This circuit dissipates 10,310.88 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 = 24 ÷ 429.62 = 0.0559 ohms.
At the same 24V, current doubles to 859.24A and power quadruples to 20,621.76W. Lower resistance means more current, which means more power dissipated as heat.
P = V × I = 24 × 429.62 = 10,310.88 watts.
All 10,310.88W 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.
