what is the relation between dielectric constant and impedance?
 

Dear karthikss42
Hi
The capacitance equation is : c=(e0*er*A/D) . it will change the value of your capacitance , and thus , the impedance will change.

but where dielectric constant concept present
 

Again hi
The e ( epsilon ) is the dielectric ratio .
