Formulas & Step-by-Step

Resistance

R = V ÷ I

100 ÷ 133.66 = 0.7482 Ω

Power

P = V × I

100 × 133.66 = 13,366 W

Verification (alternative formulas)

P = I² × R

133.66² × 0.7482 = 17,865 × 0.7482 = 13,366 W ✓

P = V² ÷ R

100² ÷ 0.7482 = 10,000 ÷ 0.7482 = 13,366 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 13,366 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.

Frequently Asked Questions

What is the resistance for 100V and 133.66A?expand_more

R = V ÷ I = 100 ÷ 133.66 = 0.7482 ohms.

How are voltage, current, resistance, and power related?expand_more

Ohm's Law (V = IR) and the power equation (P = VI) connect all four. Given any two, you can calculate the other two.

What happens if I halve the resistance?expand_more

At the same 100V, current doubles to 267.32A and power quadruples to 26,732W. Lower resistance means more current, which means more power dissipated as heat.
