The capacitance of a parallel plate condenser is C 0 . If a dielectric of relative permittivity ε r and thickness equal to one fourth the plate separation is placed between the plates, then its capacity becomes C. Then value of 
will be-
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Capacitance of capacitor without dielectric, C 0 = 
Capacitance of capacitor with dielectric, C
C = 
= 
⇒ 
= 
C = 
= 
⇒ 
=
