- B \(140 \mathrm{~V}\)
- C \(100 \mathrm{~V}\)
- D \(20 \mathrm{~V}\)
Answer & Solution
Correct Answer
(C) \(100 \mathrm{~V}\)
Step-by-step Solution
Detailed explanation
The given circuit diagram is \(L-C-R\). series circuit, where \[ \begin{aligned} &V_{R}=80 \mathrm{~V}, V_{C}=100 \mathrm{~V} \\ &V_{L}=40 \mathrm{~V} \end{aligned} \] Since, \(\quad V_{C}>V_{L}\) Value of \(\operatorname{emf} E\) is given as…
