A) \[R=1\,k\Omega ,\,\,C=10\,\mu F\]
B) \[R=1\,k\Omega ,\,\,C=1\,\mu F\]
C) \[R=1\,k\Omega ,\,\,C=10\,\mu F\]
D) \[R=1\,k\Omega ,\,\,C=1\,H\]
Correct Answer: C
Solution :
Emf of AC source \[E={{E}_{0}}\sin \,(100\,t)\] We have co = 100 and \[\phi =\frac{\pi }{4}={{45}^{o}}\] \[\tan \phi =\frac{\omega L}{R}\] \[1=\frac{100\times L}{R}\] \[R=100\,L\] If L = 10 H then \[R=1\,k\Omega \]
