Formulas & Step-by-Step

Resistance

R = V ÷ I

100 ÷ 134.58 = 0.7431 Ω

Power

P = V × I

100 × 134.58 = 13,458 W

Verification (alternative formulas)

P = I² × R

134.58² × 0.7431 = 18,111.78 × 0.7431 = 13,458 W ✓

P = V² ÷ R

100² ÷ 0.7431 = 10,000 ÷ 0.7431 = 13,458 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 13,458 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.

If You Change the Resistance

Frequently Asked Questions

What is the resistance for 100V and 134.58A?expand_more

R = V ÷ I = 100 ÷ 134.58 = 0.7431 ohms.

What happens if I halve the resistance?expand_more

At the same 100V, current doubles to 269.16A and power quadruples to 26,916W. Lower resistance means more current, which means more power dissipated as heat.
