Question

A coaxial line has an inner conductor of radius 5 mm and an outer conductor of radius 15 mm. The insulation is polystyrene (relative permittivity 2.7, breakdown electric field - 20 x 10 v/m) (a) if a voltage of 100 v is applied between the two conductors, find the electric field at the surface of each conductor (b) 1. What is the maximum voltage that can be applied to the coaxial line before dielectric breakdown occurs?
