Formulas & Step-by-Step

Resistance

R = V ÷ I

24 ÷ 680.11 = 0.0353 Ω

Power

P = V × I

24 × 680.11 = 16,322.64 W

Verification (alternative formulas)

P = I² × R

680.11² × 0.0353 = 462,549.61 × 0.0353 = 16,322.64 W

P = V² ÷ R

24² ÷ 0.0353 = 576 ÷ 0.0353 = 16,322.64 W

Circuit Analysis

Heat Dissipation

This circuit dissipates 16,322.64 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 ÷ 680.11 = 0.0353 ohms.
P = V × I = 24 × 680.11 = 16,322.64 watts.
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.
At the same 24V, current doubles to 1,360.22A and power quadruples to 32,645.28W. Lower resistance means more current, which means more power dissipated as heat.
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.
