Formulas & Step-by-Step

Resistance

R = V ÷ I

100 ÷ 14.96 = 6.68 Ω

Power

P = V × I

100 × 14.96 = 1,496 W

Verification (alternative formulas)

P = I² × R

14.96² × 6.68 = 223.8 × 6.68 = 1,496 W ✓

P = V² ÷ R

100² ÷ 6.68 = 10,000 ÷ 6.68 = 1,496 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 1,496 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 14.96A?expand_more

R = V ÷ I = 100 ÷ 14.96 = 6.68 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 determines wire size for 14.96A?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 6.68 ohms produce at 100V?expand_more

All 1,496W 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.
