Question

The plate area of a parallel plate capacitor is 0.01m2.the distance between the plates is 2.5 cm .the insulating medium is air find its capacitance if the spacepetween the plates is filled with an insulating materia of relative permittivity 5
​

Answer 1

Answer:

Capacitance will be 17.7Pf.

Explanation:

Plate area (A)=0.01m^2

Distance between the plates(d)=2.5cm=2.5×10^-2m

K=5

Hence capacitance of the capacitor in free space/Vaccum will be =A£°/d.

In a medium of relative permittivity 5 Capacitance =KA£°/d=177×10^-13F=17.7Pf.
