Formulas & Step-by-Step

Resistance

R = V ÷ I

100 ÷ 104.92 = 0.9531 Ω

Power

P = V × I

100 × 104.92 = 10,492 W

Verification (alternative formulas)

P = I² × R

104.92² × 0.9531 = 11,008.21 × 0.9531 = 10,492 W ✓

P = V² ÷ R

100² ÷ 0.9531 = 10,000 ÷ 0.9531 = 10,492 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 10,492 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.

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

What is the power for 100V and 104.92A?expand_more

P = V × I = 100 × 104.92 = 10,492 watts.

What determines wire size for 104.92A?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 0.9531 ohms produce at 100V?expand_more

All 10,492W 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.
