Formulas & Step-by-Step

Resistance

R = V ÷ I

100 ÷ 117.84 = 0.8486 Ω

Power

P = V × I

100 × 117.84 = 11,784 W

Verification (alternative formulas)

P = I² × R

117.84² × 0.8486 = 13,886.27 × 0.8486 = 11,784 W ✓

P = V² ÷ R

100² ÷ 0.8486 = 10,000 ÷ 0.8486 = 11,784 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 11,784 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.

How much heat does 0.8486 ohms produce at 100V?expand_more

All 11,784W 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.

What happens if I halve the resistance?expand_more

At the same 100V, current doubles to 235.68A and power quadruples to 23,568W. Lower resistance means more current, which means more power dissipated as heat.
