A series R - L - C circuit is shown in the diagram above. Which of the following vector diagrams correctly represents the phase relationship among I, V, V\(_F\), V\(_C\), and V\(_L\), if V\(_C\) is greater than V\(_L\) and the symbols have their usual meaning?

Verified Correct Answer: A.
Physical Principles & Numerical Solution
i.e V\(_L\) - V\(_C\) = -ve (V\(_C\) - V\(_L\) = +ve)
From Tan \(\phi\) = \(\frac{V_L - V_C}{\text{R}}\)
It shows that V\(_L\) - V\(_C\) will be inverted on the y-axis V\(_C\) > V\(_L\)
