According to Ohm's Law, voltage is equal to:

Ohm's Law states the relationship between voltage, current, and resistance in an electrical circuit. According to this law, the voltage (V) across a conductor is directly proportional to the current (I) flowing through it, and this relationship is manifested in the formula V = I × R, where R represents the resistance in the circuit.

The correct interpretation here is that voltage is the product of resistance and current. This means that if you know the current flowing through a resistor and the resistance of that resistor, you can calculate the voltage across it. This is fundamental in electrical engineering as it helps in understanding how circuits behave under different loads.

The other options do not correctly encapsulate Ohm's Law. For instance, voltage cannot be accurately represented as current times power, nor is it derived from dividing power by resistance. Each component—voltage, current, and resistance—has a specific relationship defined by Ohm's Law, making the correct formulation crucial for analysis in electrical systems.
