JEE Main 12 Jan 2019 Evening Question 15
Question: In the circuit shown, find C if the effective capacitance of the whole circuit is to be $ 0.5\mu F. $ All values in the circuit are in $ \mu F. $ [JEE Main Online Paper Held On 12-Jan-2019 Evening]
Options:
A) $ \frac{6}{5}\mu F $
B) $ 4\mu F $
C) $ \frac{7}{11}\mu F $
D) $ \frac{7}{10}\mu F $
Show Answer
Answer:
Correct Answer: C
Solution:
The given circuit can be simplified as follows:
So, $ \frac{C( \frac{7}{3} )}{\frac{7}{3}+C}=\frac{5}{10}\Rightarrow C=\frac{7}{11}\mu F $
