Please help, I have no idea where to start with this question:
voltage that can be applied between the central wire and the outer sheath.
r1=2mm
r2=5mm
r3=10mm
Region 3 (r=r2-r3)
Am I right to say that I have to use gauss's law?
A co-axial conductor comprises a high voltage central wire, a layer of oil with
a relative dielectric constant of 3, an insulator layer with a relative dielectric
constant of 5 and an outer earthed sheath (see below for the various
dimensions). The breakdown field for the oil is 2.8 MVm
a relative dielectric constant of 3, an insulator layer with a relative dielectric
constant of 5 and an outer earthed sheath (see below for the various
dimensions). The breakdown field for the oil is 2.8 MVm
-1 and the
breakdown field for the insulator is 4.2 MVm-1. Calculate the maximum
breakdown field for the insulator is 4.2 MVm-1. Calculate the maximum
voltage that can be applied between the central wire and the outer sheath.
