Formulas & Step-by-Step

Resistance

R = V ÷ I

120 ÷ 1,007.49 = 0.1191 Ω

Power

P = V × I

120 × 1,007.49 = 120,898.8 W

Verification (alternative formulas)

P = I² × R

1,007.49² × 0.1191 = 1,015,036.1 × 0.1191 = 120,898.8 W ✓

P = V² ÷ R

120² ÷ 0.1191 = 14,400 ÷ 0.1191 = 120,898.8 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 120,898.8 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 120V and 1,007.49A?expand_more

R = V ÷ I = 120 ÷ 1,007.49 = 0.1191 ohms.

Does Ohm's Law work for AC circuits?expand_more

For purely resistive loads, yes. For reactive loads, use impedance (Z) instead of resistance (R). Z includes both resistance and reactance, and the V/I phase shift shows up in power factor.

What are all 12 Ohm's Law formulas?expand_more

V=IR, V=P/I, V=√(PR) | I=V/R, I=P/V, I=√(P/R) | R=V/I, R=V²/P, R=P/I² | P=VI, P=I²R, P=V²/R.
