Formulas & Step-by-Step

Resistance

R = V ÷ I

24 ÷ 496.86 = 0.0483 Ω

Power

P = V × I

24 × 496.86 = 11,924.64 W

Verification (alternative formulas)

P = I² × R

496.86² × 0.0483 = 246,869.86 × 0.0483 = 11,924.64 W

P = V² ÷ R

24² ÷ 0.0483 = 576 ÷ 0.0483 = 11,924.64 W

Circuit Analysis

Heat Dissipation

This circuit dissipates 11,924.64 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 ÷ 496.86 = 0.0483 ohms.
All 11,924.64W 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.
At the same 24V, current doubles to 993.72A and power quadruples to 23,849.28W. Lower resistance means more current, which means more power dissipated as heat.
P = V × I = 24 × 496.86 = 11,924.64 watts.
For purely resistive loads, yes. For reactive loads, use impedance (Z) instead of resistance (R). Z includes both resistance and reactance, and the V/I phase shift shows up in power factor.
