Formulas & Step-by-Step

Resistance

R = V ÷ I

24 ÷ 237.91 = 0.1009 Ω

Power

P = V × I

24 × 237.91 = 5,709.84 W

Verification (alternative formulas)

P = I² × R

237.91² × 0.1009 = 56,601.17 × 0.1009 = 5,709.84 W

P = V² ÷ R

24² ÷ 0.1009 = 576 ÷ 0.1009 = 5,709.84 W

Circuit Analysis

Heat Dissipation

This circuit dissipates 5,709.84 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.

P = V × I = 24 × 237.91 = 5,709.84 watts.
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.
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.
Ohm's Law (V = IR) and the power equation (P = VI) connect all four. Given any two, you can calculate the other two.
