A) \[0.52\,\,\sin \,\,314\,\,t\]
B) \[5.2\,\cos \,\,314\,t\]
C) \[10\,\cos \,\,314\,t\]
D) \[0.52\,\,\cos \,\,314\,t\]
Correct Answer: D
Solution :
[d] \[Z={{x}_{C}}-{{x}_{L}}\] |
\[Z=\frac{1}{\omega C}-\omega L\] |
\[=\frac{1}{314\times 100\times {{10}^{-6}}}-314\times 40\times {{10}^{-3}}\] |
\[=19.28\,\Omega \] |
\[i=\frac{{{V}_{0}}}{Z}\,\,\sin \,\,(\omega t+\pi /2)\] |
