Quizplus · Accepted Answer

Ohm's law states that I = V/R, where I is the current in amps (A), V is the voltage in volts (V), and R is the resistance in ohms (Ω).

In the given circuit, the voltage is 12 V and the resistance is 3 Ω.

So, I = 12/3 = 4 A.

Therefore, the correct answer is choice D - 4 A.
