Formulas & Step-by-Step

Resistance

R = V ÷ I

24 ÷ 239.45 = 0.1002 Ω

Power

P = V × I

24 × 239.45 = 5,746.8 W

Verification (alternative formulas)

P = I² × R

239.45² × 0.1002 = 57,336.3 × 0.1002 = 5,746.8 W ✓

P = V² ÷ R

24² ÷ 0.1002 = 576 ÷ 0.1002 = 5,746.8 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 5,746.8 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

What is the resistance for 24V and 239.45A?expand_more

R = V ÷ I = 24 ÷ 239.45 = 0.1002 ohms.

How much heat does 0.1002 ohms produce at 24V?expand_more

All 5,746.8W 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.

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.
