Question

The power dissipated within the dielectric at an operating frequency of 9 ghz is

Answer 1

Answer:

When the dielectric used is vacuum, then the capacitance Co = ε o (A/d), where ε o is the permittivity of vacuum (8.85 x 10-12 F/m ). The dielectric constant (k) of a material is the ratio of its permittivity ε to the permittivity of vacuum ε o , so k = ε / ε o.

i hope this will help uhh
