Electrostatics Question 39
Question: The capacity and the energy stored in a parallel plate condenser with air between its plates are respectively and . If the air is replaced by glass (dielectric constant = 5) between the plates, the capacity of the plates and the energy stored in it will respectively be
Options:
A)
B)
C)
D)
Show Answer
Answer:
Correct Answer: B
Solution:
When a dielectric K is introduced in a parallel plate condenser its capacity becomes K times.
Hence
Energy stored
therefore
