Formulas & Step-by-Step

Resistance

R = V ÷ I

24 ÷ 988.51 = 0.0243 Ω

Power

P = V × I

24 × 988.51 = 23,724.24 W

Verification (alternative formulas)

P = I² × R

988.51² × 0.0243 = 977,152.02 × 0.0243 = 23,724.24 W

P = V² ÷ R

24² ÷ 0.0243 = 576 ÷ 0.0243 = 23,724.24 W

Circuit Analysis

Heat Dissipation

This circuit dissipates 23,724.24 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

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.
Wire sizing for a given current is not an Ohm's Law calculation. It depends on run length, source voltage, voltage-drop target, conductor material, insulation and termination temperature rating, cable type, and ambient and bundling conditions. The dedicated wire-size calculator takes those variables as input.
Ohm's Law (V = IR) and the power equation (P = VI) connect all four. Given any two, you can calculate the other two.
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.
