Homework 4 A cylindrical capacitor consists of an inner conductor of radius a and an outer conductor whose inner radius is b. The space between the conductors is filled with a dielectric of permittivity &₁, 2 and the length of the capacitor is L. Determine the capacitance of this capacitor C/L. 無限長的同軸傳輸線,內部導體及外部導體之半徑分別為a及b,其間之介電質其介電 係數在 a<r<c 之間是 q,在 c<r<b 是 ,而 a<c<b,試求其單位長度之電容。 -9 W LE*# › HÀ & D. ds = q + (1) a<r<c+ (&E₁) (27rL)=q, E₁= + (2) c<r<b.
