If \(L , C\) and \(R\) are the self inductance, capacitance and resistance respectively, which of the following does not have the dimension of time?
- A \(RC\)
- B \(\frac{L}{R}\)
- C \(\sqrt{ LC }\)
- D \(\frac{L}{C}\)
Answer & Solution
Correct Answer
(D) \(\frac{L}{C}\)
Step-by-step Solution
Detailed explanation
\(\left(\frac{L}{C}\right)\) does not have dimension of time. \(RC , \frac{ L }{ R }\) are time constant while \(\sqrt{ LC }\) is reciprocal of angular frequency or having dimension of time.
