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

To determine the total current in a circuit when the voltage and resistance are known, you can apply Ohm's Law. Ohm's Law states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor. The formula is expressed as:

[ I = \frac{V}{R} ]

In this scenario, the voltage is given as 120 volts and the resistance is 30 ohms. By substituting these values into the formula, you have:

[ I = \frac{120: \text{volts}}{30: \text{ohms}} ]

Calculating this gives:

[ I = 4: \text{amps} ]

This means that the correct amount of current present in the circuit is 4 amps. Based on the multiple-choice options, the answer that reflects the calculation is 4 amps.

The choice of 12 amps, while it may seem plausible at a glance, deviates from the correct calculation derived from Ohm’s Law. Therefore, the original conclusion about the total current should emphasize that it is indeed 4 amps based on the proper
