Question) If a dielectric with εr1=3 is laminated in region 1
where the cross-sectional structure of the coaxial line is 2 ≦ ρ ≦
3 [m] as shown in the figure below,
and a dielectric with εr2=2 is laminated in region 2 where 1 ≦ ρ ≦
2 [m], find the values of (a), (b), (c), and (d).
(a) If the external conductor has a total charge of -Q=-1×10^-9
[C], and the length of the coaxial line is l=1[m], what [V/m] is
the magnitude of the electric field E1 at the position ρ=2.5[m]
obtained by Gaussian theorem?
ANSWER : ? [V/m]
(b) If the external conductor has a total charge of Q=1×10^-9
[C], and the length of the coaxial line is l=1[m], what [V/m] is
the magnitude of the electric field E2 at the position ρ=1.5[m]
obtained by Gaussian theorem?
ANSWER : ? [V/m]
(c) If the length of the coaxial line from the previously
obtained electric field is l = 1 [m], what is the potential
difference between the two coaxial conductors?
ANSWER : ? [V]
(d) If the length of the coaxial line is l=1[m], what [nF] is
the capacitance C?
ANSWER : ? [nF]
