To calculate the current in Amps using Ohm's Law, you can utilize the formula that expresses the relationship between voltage (Volts), current (Amps), and resistance (Ohms). Ohm's Law states that current (I) is equal to voltage (V) divided by resistance (R). Therefore, if you know the voltage and the resistance, you can find the current by rearranging the formula as follows:

I = V / R

This indicates that current is directly proportional to the voltage applied and inversely proportional to the resistance in the circuit. So when you divide the voltage by the resistance, you get the current in Amps.

In contrast, the other options provide incorrect methods of calculating current. Multiplying voltage by resistance or incorrectly manipulating the formula results in calculations that do not adhere to the principles of electrical circuits as defined by Ohm's Law.
