Formulas & Step-by-Step

Resistance

R = V ÷ I

100 ÷ 88.1 = 1.14 Ω

Power

P = V × I

100 × 88.1 = 8,810 W

Verification (alternative formulas)

P = I² × R

88.1² × 1.14 = 7,761.61 × 1.14 = 8,810 W ✓

P = V² ÷ R

100² ÷ 1.14 = 10,000 ÷ 1.14 = 8,810 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 8,810 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.

R = V ÷ I = 100 ÷ 88.1 = 1.14 ohms.

How much heat does 1.14 ohms produce at 100V?expand_more

All 8,810W 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.
