What does R1 represent in the resistance formula?

Explanation:
R1 is the resistance of the first component. It’s the opposition that this component provides to the flow of current, defined by R1 = V1 / I1, where V1 is the voltage across the first component and I1 is the current through it. This makes R1 a property of that specific component, not the voltage across it, not the second component, and not the total circuit resistance. Remember, the total resistance depends on how components are connected, but R1 itself is simply the first component’s ohmic value (in ohms).
