Formulas & Step-by-Step

Resistance

R = V ÷ I

100 ÷ 149.99 = 0.6667 Ω

Power

P = V × I

100 × 149.99 = 14,999 W

Verification (alternative formulas)

P = I² × R

149.99² × 0.6667 = 22,497 × 0.6667 = 14,999 W ✓

P = V² ÷ R

100² ÷ 0.6667 = 10,000 ÷ 0.6667 = 14,999 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 14,999 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.
