What is the equation for Ohm's Law?

• A. V = P/I
• B. V = IR
• C. R = VI
• D. I = V/R

Answer: (B)

Ohm's Law is fundamental in understanding the relationship between voltage, current, and resistance in an electrical circuit. The correct equation, represented as V = IR, denotes that voltage (V) is equal to current (I) multiplied by resistance (R). This means that for a given resistance, if you increase the current, the voltage across that resistance also increases proportionally. This relationship helps to analyze circuits and troubleshoot issues pertaining to electrical flow. It clearly illustrates how each component affects the others, providing a basis for calculations in electrical engineering and electronics. Understanding this equation is crucial for those working with pacemakers and other electronic medical devices, where controlling electrical parameters is vital for functionality and patient safety.
