Question

12. A parallel plate air capacitor has capacitance 5 uF. It is charged by connecting to a 50 V battery. Now
the battery is disconnected from the circuit and the space between the two plates of the capacitor is filled
with a dielectric medium. The S.I.C. of the medium is 5. Compare (a) charge, (b) capacitance and (c) potential
difference of the capacitor before and after filling it with the medium​

Answer 1

Step-by-step explanation:

The capacitance of a capacitor when dielectric constant K is introduced is

C=KC

0

, where C

0

is the capacitance without dielectric constant.

So,

50=K×5

K=10
