Question

When a dielectric material is introduced between the plates of a parallel-plate capacitor and completely fills the space, the capacitance increases by a factor of 5. What is the dielectric constant of the material that was introduced? None of the other choices is correct. 25 1/5 un 1/25

Answer 1

We know for this case capacitance =kAe/d

Where k is dielectric constant.

So here capacitance is directly proportional yo dielectric constant.

Here when dielectric material introduce all other factore reamins same except capacitance.

So , capacitance increases by factor 5 when we introduce a material of dielectric constant 5.

Dielectric constant =5.
