To find the resulting current when 120 volts are applied to a circuit with a resistance of 60 ohms, Ohm's Law is applied, which states that current (I) is equal to voltage (V) divided by resistance (R).

In this case, you would use the formula:

I = V / R

Substituting in the values provided:

I = 120 volts / 60 ohms

Calculating this gives:

I = 2 amps

This means that when 120 volts are applied across a resistance of 60 ohms, the current flowing through the circuit will be 2 amps. This demonstrates the relationship described by Ohm's Law and illustrates how voltage, resistance, and current are interconnected in electrical circuits.
