Electro Magnetic Induction And Alternating Currents Question 39
Question: In a series resonant circuit, the ac voltage across resistance R, inductance L and capacitance C are 5 V, 10 V and 10 V respectively. The ac voltage applied to the circuit will be [KCET 1994]
Options:
A) 20 V
B) 10 V
C) 5 V
D) 25 V
Show Answer
Answer:
Correct Answer: C
Solution:
$ V=\sqrt{V_{R}^{2}+{{(V_{L}-V_{C})}^{2}}}=\sqrt{{{(5)}^{2}}+{{(10-10)}^{2}}}=5Volt $
