Which of the following components of an \(L-C-R\) circuit, with an AC supply, dissipates energy?
- A Only \(L\)
- B Only \(R\)
- C Only \(C\)
- D \(L\) and \(C\)
Answer & Solution
Correct Answer
(B) Only \(R\)
Step-by-step Solution
Detailed explanation
In an AC-circuit, the power or rate of energy dissipated is \(P=V I \cos \phi\) where, \(\phi=\) phase difference between voltage and current. For inductor \((L)\) and capacitor \((C)\), the phase difference between \(V\) and \(I\) is \(90^{\circ}\).…
