What is the required resistance to limit the current to 2 amps in a 120 volt circuit?

To determine the required resistance to limit the current to 2 amps in a 120-volt circuit, we can use Ohm's Law, which states that Voltage (V) equals Current (I) multiplied by Resistance (R), or V = I * R.

Rearranging this formula allows us to solve for resistance: R = V / I.

Substituting in the given values:

R = 120 volts / 2 amps = 60 ohms.

This calculation shows that a resistance of 60 ohms is necessary to achieve the desired current of 2 amps when connected to a 120-volt source. This is why the correct answer is based on such mathematical reasoning derived from Ohm's Law, which is a fundamental principle in electrical theory.
