A) 130 V
B) 10 V
C) 50 V
D) 70 V
Correct Answer: C
Solution :
Resultant potential difference (supply voltage of an LCR circuit is \[V=\sqrt{V_{R}^{2}+{{({{V}_{L}}-{{V}_{C}})}^{2}}}\] \[=\sqrt{{{(40)}^{2}}+{{(60-30)}^{2}}}\] \[=\sqrt{{{(40)}^{2}}+({{30}^{2}})}\] \[=\sqrt{{{(50)}^{2}}}\] \[=50\,volt\]You need to login to perform this action.
