Formulas & Step-by-Step

Resistance

R = V ÷ I

100 ÷ 17.63 = 5.67 Ω

Power

P = V × I

100 × 17.63 = 1,763 W

Verification (alternative formulas)

P = I² × R

17.63² × 5.67 = 310.82 × 5.67 = 1,763 W ✓

P = V² ÷ R

100² ÷ 5.67 = 10,000 ÷ 5.67 = 1,763 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 1,763 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.
