To determine the current in Amps using Ohm's Law, which states that voltage (V) equals current (I) multiplied by resistance (R), you can rearrange the formula to find current: I = V / R.

In this scenario, you have a voltage of 120 volts and a resistance of 25 ohms. By plugging these values into the rearranged formula:

I = 120 volts / 25 ohms = 4.8 Amps.

This calculation shows that the current flowing through a circuit with 120 volts and 25 ohms of resistance is indeed 4.8 Amps. This demonstrates the practical application of Ohm's Law in determining electrical parameters in a circuit. Understanding this law is crucial for anyone working with electrical systems, as it serves as the foundation for analyzing and troubleshooting circuit behavior.
