Formulas & Step-by-Step

Resistance

R = V ÷ I

24 ÷ 675.03 = 0.0356 Ω

Power

P = V × I

24 × 675.03 = 16,200.72 W

Verification (alternative formulas)

P = I² × R

675.03² × 0.0356 = 455,665.5 × 0.0356 = 16,200.72 W

P = V² ÷ R

24² ÷ 0.0356 = 576 ÷ 0.0356 = 16,200.72 W

Circuit Analysis

Heat Dissipation

This circuit dissipates 16,200.72 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 ÷ 675.03 = 0.0356 ohms.
P = V × I = 24 × 675.03 = 16,200.72 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.
All 16,200.72W 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.
Ohm's Law (V = IR) and the power equation (P = VI) connect all four. Given any two, you can calculate the other two.
