A) \[2500\,rad-{{s}^{-1}}\] and \[5\sqrt{2}\,A\]
B) \[2500\,rad-{{s}^{-1}}\] and \[5A\]
C) \[2500\,rad-{{s}^{-1}}\] and \[\frac{5}{\sqrt{2}}A\]
D) \[25\,rad-{{s}^{-1}}\] and \[5\sqrt{2}\,A\]
Correct Answer: B
Solution :
Resonance frequency \[\omega =\frac{1}{\sqrt{LC}}=\frac{1}{\sqrt{8\times {{10}^{-3}}\times 20\times {{10}^{-6}}}}=2500\ rad/\sec \] Resonance current = \[\frac{V}{R}=\frac{220}{44}=5A\]You need to login to perform this action.
