What Is the Resistance and Power for 100V and 149.98A?

100 volts and 149.98 amps gives 0.6668 ohms resistance and 14,998 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 ÷ 149.98 = 0.6668 Ω

Power

P = V × I

100 × 149.98 = 14,998 W

Verification (alternative formulas)

P = I² × R

149.98² × 0.6668 = 22,494 × 0.6668 = 14,998 W

P = V² ÷ R

100² ÷ 0.6668 = 10,000 ÷ 0.6668 = 14,998 W

Circuit Analysis

Heat Dissipation

This circuit dissipates 14,998 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.
All 14,998W 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.
P = V × I = 100 × 149.98 = 14,998 watts.
