Formulas & Step-by-Step

Resistance

R = V ÷ I

24 ÷ 182.1 = 0.1318 Ω

Power

P = V × I

24 × 182.1 = 4,370.4 W

Verification (alternative formulas)

P = I² × R

182.1² × 0.1318 = 33,160.41 × 0.1318 = 4,370.4 W ✓

P = V² ÷ R

24² ÷ 0.1318 = 576 ÷ 0.1318 = 4,370.4 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 4,370.4 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.

Does Ohm's Law work for AC circuits?expand_more

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.

How much heat does 0.1318 ohms produce at 24V?expand_more

All 4,370.4W 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.
