Question

a parallel plate capacitor has a capacitance of 2uF in air and 12uF when immersed in oil the dielectric constant of the oil is​

Answer 1

Answer:

the same time as a great day

Answer 2

Explanation:

Let before immersed in oil the capacitance is C , potential is V.

and field , E=V/d where d= separation of plates.

After immersed in oil the capacitance becomes C

′

=kC=2C and potential becomes V

′

=V/2 becasuse C=

V

Q

.

Now filed , E

=V
