What Is the Resistance and Power for 100V and 98.37A?

100 volts and 98.37 amps gives 1.02 ohms resistance and 9,837 watts power. Ohm's Law (V = IR) and the power equation (P = VI) connect all four electrical values. Knowing any two lets you calculate the other two instantly.

Formulas & Step-by-Step

Resistance

R = V ÷ I

100 ÷ 98.37 = 1.02 Ω

Power

P = V × I

100 × 98.37 = 9,837 W

Verification (alternative formulas)

P = I² × R

98.37² × 1.02 = 9,676.66 × 1.02 = 9,837 W

P = V² ÷ R

100² ÷ 1.02 = 10,000 ÷ 1.02 = 9,837 W

Circuit Analysis

Heat Dissipation

This circuit dissipates 9,837 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

R = V ÷ I = 100 ÷ 98.37 = 1.02 ohms.
Ohm's Law (V = IR) and the power equation (P = VI) connect all four. Given any two, you can calculate the other two.
All 9,837W 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.
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.
