A) \[\text{10/}\sqrt{\text{2}}\,\text{V}\]
B) \[20\sqrt{\text{2}}\,\text{V}\]
C) \[10\sqrt{\text{2}}\]
D) \[10\,\text{V}\]
Correct Answer: C
Solution :
Given, \[{{V}_{L}}={{V}_{C}}={{V}_{R}}=10volt.\] \[\therefore \] \[V=\sqrt{V_{R}^{2}+{{({{V}_{L}}-{{V}_{C}})}^{2}}}\] \[V={{V}_{R}}\] (As \[{{V}_{L}}={{V}_{C}}\]) When C is short circuited, \[V=\sqrt{V_{R}^{2}+V_{L}^{2}}\] \[=\sqrt{{{(10)}^{2}}+{{(10)}^{2}}}\] \[=10\sqrt{2}volt.\]
