Formulas & Step-by-Step

Resistance

R = V ÷ I

24 ÷ 10.56 = 2.27 Ω

Power

P = V × I

24 × 10.56 = 253.44 W

Verification (alternative formulas)

P = I² × R

10.56² × 2.27 = 111.51 × 2.27 = 253.44 W ✓

P = V² ÷ R

24² ÷ 2.27 = 576 ÷ 2.27 = 253.44 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 253.44 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.

How much heat does 2.27 ohms produce at 24V?expand_more

All 253.44W 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.
