If voltage is 120V and resistance is 24 ohms, current is

Explanation:
Current is 5 amperes. Using Ohm’s law, I = V/R, plug in 120 V and 24 Ω to get 120 ÷ 24 = 5 A. This makes sense: with a fixed voltage, increasing resistance lowers current. A quick check of power also fits: P = VI = 120 × 5 = 600 W, or P = I^2R = 25 × 24 = 600 W.
