Question

The electrical capacity of a parallel plate capacitor is 20 mF.If the space between the two plates is

completely filled with a dielectric medium the capacity increases to 45 mF. Find the dielectric constant of material medium​

Answer 1

Answer:

Explanation:

Capacitance of capacitor C=20μF

=20×10 −6 F

Rate of change of potential is, DV/DT=3v/s

q=CV

DQ/DT=c(DV/DT)

ie

=20×10−6 ×3  

=60×10  −6  A

=60μA
