A) \[\frac{250}{\pi }\]
B) \[\frac{200}{\pi }\]
C) \[\frac{100}{\pi }\]
D) \[\frac{500}{\pi }\]
Correct Answer: D
Solution :
For \[{{P}_{max}},\]i should be max \[\Rightarrow \,{{X}_{L}}={{X}_{C}}\] \[\Rightarrow \,\omega L=\frac{1}{\omega C}\] \[\Rightarrow \,2\pi fL=\frac{1}{2\pi fC}\] \[f=\frac{1}{2\pi \sqrt{LC}}\] \[\Rightarrow \,\frac{1}{2\pi \sqrt{25\times {{10}^{-3}}\times 40\times {{10}^{-6}}}}\]You need to login to perform this action.
