Which of the following equations represents Ohm's Law?

Ohm's Law describes the relationship between current, voltage, and resistance in an electrical circuit. The law is articulated by the equation I = V/R, where I represents current (in amperes), V represents voltage (in volts), and R represents resistance (in ohms). This formulation shows that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance of the circuit.

This equation allows users to calculate the current that will flow through a circuit for a given voltage and resistance, which is fundamental in electrical engineering and physics. It's essential for understanding how electrical components behave in various configurations.

In contrast, the other equations presented do not accurately represent Ohm's Law. For instance, while R = V/I can be derived from rearranging I = V/R, it is not the most commonly recognized form of Ohm's Law. Similarly, I = V * R is incorrect as it suggests a direct multiplication rather than division, leading to misunderstandings regarding the relationship between these electrical quantities. Finally, V = I + R is not an accurate statement in the context of Ohm's Law, as it does not relate voltage, current, and resistance correctly.
