Question

Two types of dielectric materials are inserted between cylindrical conductors with radius

Answer 1

hi

Two types of dielectric material are inserted between cylindrical conductors with radius a, length L, and radius c, length L (Figure 6).

Calculate the following when the dielectric rate of a section (a<ρ≤b) is εb, and the dielectric rate of section (b<ρ<c) is εc.

a) When an internal conductor has a charge of Q, an external conductor has a charge of -Q, calculate the inside surface charge density of ρa and the outer surface charge density of ρc respectively.

b) Find Electric Field E in Zone (a<ρ≤b) and (b<ρ<c) respectively.

c) Find the potential difference between the two conductors

d) Use the above results to obtain Capacitance.

hope it helps
