What is the basic formula associated with Ohm's law?

• A. I = R/E
• B. I = E/R
• C. R = EI
• D. R = IE

Answer: (B)

Ohm's Law relates the voltage (E), current (I), and resistance (R) in an electrical circuit and is fundamental in understanding how these three quantities interact. The correct formulation states that current (I) is equal to voltage (E) divided by resistance (R). This relationship can be expressed as I = E/R. In this formula, voltage is the potential difference that drives the current through the resistance, and resistance is the opposition to the flow of current. Understanding this relationship allows for the calculation of one of these variables when the other two are known, playing a crucial role in circuit analysis and design. This foundational concept is essential for anyone involved in electrical work or studying electrical engineering. The other options provided do not accurately represent the fundamental relationship outlined by Ohm's Law, which is why they do not serve as a correct formula.
