Formulas & Step-by-Step

Resistance

R = V ÷ I

100 ÷ 135.36 = 0.7388 Ω

Power

P = V × I

100 × 135.36 = 13,536 W

Verification (alternative formulas)

P = I² × R

135.36² × 0.7388 = 18,322.33 × 0.7388 = 13,536 W ✓

P = V² ÷ R

100² ÷ 0.7388 = 10,000 ÷ 0.7388 = 13,536 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 13,536 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.

What determines wire size for 135.36A?expand_more

Wire sizing for a given current is not an Ohm's Law calculation. It depends on run length, source voltage, voltage-drop target, conductor material, insulation and termination temperature rating, cable type, and ambient and bundling conditions. The dedicated wire-size calculator takes those variables as input.

What happens if I halve the resistance?expand_more

At the same 100V, current doubles to 270.72A and power quadruples to 27,072W. Lower resistance means more current, which means more power dissipated as heat.
