As we have learned

Dielectric Constant (K) -

K=\frac{E}{{E}'}

 

- wherein

K is also known as relative permetivity \left (\varepsilon _{r} \right ).

 

 High K means good insulating property and high x means able to withstand electric field gradient to a higher value.

 


Option 1)

High k and high  x

Option 2)

High k and low x

Option 3)

            Low k and low x

Option 4)

Low k and high x
