Electro Magnetic Induction And Alternating Currents Question 6
Question: A resonant ac circuit contains a capacitor of capacitance $ {{10}^{-6}}F $ and an inductor of $ {{10}^{-4}}H. $ The frequency of electrical oscillations will be
Options:
A) $ 10^{5},Hz $
B) 10 Hz
C) $ \frac{10^{5}}{2\pi }Hz $
D) $ \frac{10}{2\pi }Hz $
Show Answer
Answer:
Correct Answer: C
Solution:
$ \nu =\frac{1}{2\pi \sqrt{LC}}=\frac{1}{2\pi \sqrt{{{10}^{-6}}\times {{10}^{-4}}}}=\frac{10^{5}}{2\pi }Hz $
