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

The correct answer is 12 voltage 3*4=12

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.
