Q2) In a co-axial cable, the outer radius and the applied voltage are constant as r2= 8.4 cm and U = 220 kV. The range of ri to have partial discharge is 0<$2 cm. a) Find the range of r to have total breakdown. b) Find the range of ri to have no discharge. ( c) Sketch the curve of change in Emax with respect to ri and specify breakdown behavior in different regions. (Sketch an accurate graph by identifving important values. No mark will be allocated for the general shape of the graph.)
