How is current expressed in the final calculations of Ohm's Law?

In the context of Ohm's Law, current is expressed in Amperes. Ohm's Law itself is a fundamental principle in electrical engineering that states the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit. The law can be formulated as:

[ V = I \times R ]

In this equation, current (I) is the quantity of electric charge flowing per unit time through a conductor. The unit of measurement for current is the Ampere, often abbreviated as "A." This unit signifies that one Ampere is equal to one coulomb of charge passing through a point in the circuit per second.

Understanding that current needs to be measured in Amperes is essential for calculating the flow of electricity in circuits, especially when applying Ohm's Law to determine how voltages and resistance affect the flow of current. The other units listed—Volts (for voltage), Ohms (for resistance), and Watts (for power)—reflect different aspects of electrical calculations, but they do not measure current itself. Thus, the correct expression for current according to Ohm's Law is indeed Amperes.
