Formulas & Step-by-Step

Resistance

R = V ÷ I

100 ÷ 137.1 = 0.7294 Ω

Power

P = V × I

100 × 137.1 = 13,710 W

Verification (alternative formulas)

P = I² × R

137.1² × 0.7294 = 18,796.41 × 0.7294 = 13,710 W ✓

P = V² ÷ R

100² ÷ 0.7294 = 10,000 ÷ 0.7294 = 13,710 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 13,710 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.

All 13,710W 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.
