What is the correct calculation for voltage, if the resistance is 3 ohms and the current is 4 amps?

We are tasked to solve the correct calculation for voltage considering that the resistance is 3 ohms and the magnitude of the current is 4 amperes. To solve this problem, we need to apply Ohm's law such as V = IR where "V" represents the voltage, the "I" represents the current and "R" represents the resistance value. The solution is shown below:
I = 4 ampere
R = 3 ohms
Solving for V, we have it:
V = 3 ohms * 4 amperes
V = 12 volts

The answer for correct voltage calculation is 12 volts.
