The capacitance of a parallel plate capacitor is 
. When a glass slab is placed between the plates, the potential difference reduces to 1/8th of the original value. What is the dielectric constant of glass?
Text Solution
Verified by ExpertsThe correct answer is:
B
Potential, 
or 
V has reduced to 
th its original value. Therefore, C has increased 8 times, i.e.
