What is Ohm's Law formula?

• A. V = I / R
• B. V = I + R
• C. V = I × R
• D. V = R / I

Answer: (C)

Ohm's Law defines the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit. The correct formula, which states that voltage equals current multiplied by resistance, is represented as V = I × R. This means that if you know the current flowing through a conductor and the resistance offered by that conductor, you can calculate the voltage across it. The direct proportionality indicated by this formula highlights that as current increases, voltage will also increase, provided that resistance remains constant. In practical terms, this is critical for designing and understanding electrical circuits, as it allows engineers and electricians to determine how much voltage is required to push a certain amount of current through a given resistance. This relationship is fundamental in electrical engineering and aids in troubleshooting circuit conditions as well.
