Which of the following formulas represents voltage?

The formula that accurately represents voltage in the context of electrical circuits is found in Ohm’s Law, which states that Voltage (V) is equal to Current (I) multiplied by Resistance (R). This relationship illustrates that if you increase the current flowing through a conductor at a constant resistance, the voltage across that conductor will also increase proportionally. This formula is fundamental in understanding how electrical systems operate, whether in simple circuits or more complex applications.

The direct multiplication of current and resistance is a key concept that underpins the behavior of electrical components, enabling calculations that ensure systems are designed and analyzed effectively for safe and efficient operation.
