Formulas & Step-by-Step

Resistance

R = V ÷ I

24 ÷ 57.34 = 0.4186 Ω

Power

P = V × I

24 × 57.34 = 1,376.16 W

Verification (alternative formulas)

P = I² × R

57.34² × 0.4186 = 3,287.88 × 0.4186 = 1,376.16 W ✓

P = V² ÷ R

24² ÷ 0.4186 = 576 ÷ 0.4186 = 1,376.16 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 1,376.16 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.
