Formulas & Step-by-Step

Resistance

R = V ÷ I

24 ÷ 466.2 = 0.0515 Ω

Power

P = V × I

24 × 466.2 = 11,188.8 W

Verification (alternative formulas)

P = I² × R

466.2² × 0.0515 = 217,342.44 × 0.0515 = 11,188.8 W

P = V² ÷ R

24² ÷ 0.0515 = 576 ÷ 0.0515 = 11,188.8 W

Circuit Analysis

Heat Dissipation

This circuit dissipates 11,188.8 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 ÷ 466.2 = 0.0515 ohms.
All 11,188.8W 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.
P = V × I = 24 × 466.2 = 11,188.8 watts.
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.
