Formulas & Step-by-Step

Resistance

R = V ÷ I

100 ÷ 104.94 = 0.9529 Ω

Power

P = V × I

100 × 104.94 = 10,494 W

Verification (alternative formulas)

P = I² × R

104.94² × 0.9529 = 11,012.4 × 0.9529 = 10,494 W ✓

P = V² ÷ R

100² ÷ 0.9529 = 10,000 ÷ 0.9529 = 10,494 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 10,494 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 is the power for 100V and 104.94A?expand_more

P = V × I = 100 × 104.94 = 10,494 watts.

What determines wire size for 104.94A?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.

How much heat does 0.9529 ohms produce at 100V?expand_more

All 10,494W is dissipated as heat in a pure resistor at steady state. The 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.
