Formulas & Step-by-Step

Resistance

R = V ÷ I

24 ÷ 372.02 = 0.0645 Ω

Power

P = V × I

24 × 372.02 = 8,928.48 W

Verification (alternative formulas)

P = I² × R

372.02² × 0.0645 = 138,398.88 × 0.0645 = 8,928.48 W

P = V² ÷ R

24² ÷ 0.0645 = 576 ÷ 0.0645 = 8,928.48 W

Circuit Analysis

Heat Dissipation

This circuit dissipates 8,928.48 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 ÷ 372.02 = 0.0645 ohms.
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.
P = V × I = 24 × 372.02 = 8,928.48 watts.
At the same 24V, current doubles to 744.04A and power quadruples to 17,856.96W. Lower resistance means more current, which means more power dissipated as heat.
V=IR, V=P/I, V=√(PR) | I=V/R, I=P/V, I=√(P/R) | R=V/I, R=V²/P, R=P/I² | P=VI, P=I²R, P=V²/R.
