Formulas & Step-by-Step

Resistance

R = V ÷ I

100 ÷ 17.67 = 5.66 Ω

Power

P = V × I

100 × 17.67 = 1,767 W

Verification (alternative formulas)

P = I² × R

17.67² × 5.66 = 312.23 × 5.66 = 1,767 W ✓

P = V² ÷ R

100² ÷ 5.66 = 10,000 ÷ 5.66 = 1,767 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 1,767 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.
