Electrostatics Question 549
Question: Two condensers of capacities $ 1\mu F $ and$ 2\mu F $ are connected in series and the system is charged to$ 120\ volts $ . Then the P.D. on $ 1\mu F $ capacitor (in volts) will be [MP PMT 1987]
Options:
A) 40
B) 60
C) 80
D) 120
Show Answer
Answer:
Correct Answer: C
Solution:
Charges developed are same so $ C _{1}V _{1}=C _{2}V _{2} $
therefore $ \frac{V _{1}}{V _{2}}=2 $
$ V _{1}+V _{2}=120 $
therefore $ V _{1}=80volts $
