What would be the total current if the voltage is 120 volts and the resistance is 30 ohms?

To determine the total current flowing through a circuit, you can use Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R). In this case, the voltage is given as 120 volts, and the resistance is 30 ohms.

Using the formula:

I = V / R

Substituting in the values:

I = 120 volts / 30 ohms

Calculating this gives:

I = 4 amps

Therefore, the correct answer is actually 4 amps, indicating the total current in the circuit. The choice of 12 amps, while relating to a higher current value, is incorrect based on the specific voltage and resistance provided and does not align with the understanding of Ohm's Law in this context.
