Formulas & Step-by-Step

Resistance

R = V ÷ I

100 ÷ 17.69 = 5.65 Ω

Power

P = V × I

100 × 17.69 = 1,769 W

Verification (alternative formulas)

P = I² × R

17.69² × 5.65 = 312.94 × 5.65 = 1,769 W ✓

P = V² ÷ R

100² ÷ 5.65 = 10,000 ÷ 5.65 = 1,769 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 1,769 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.
