Q. 2: V=25kV has been applied to the three-layer cylindrical electrode
system with a length of 180 meters. Layer thicknesses have been
given as ri-2cm, r-2.4cm, r3=2.6cm, R=3.2cm, respectively.
Insulating oil has been placed in the first and third layers, and a
paraffin paper has been placed in the second layer, and the
dielectric constants have been given Eri=8r3=2,2 and &r2-2.
(8o=8,854×1012F/m)
a) Find the capacity of each layer?
b) Calculate the voltage of the layers?
c) Calculate the electrical field of the layers?
d) Calculate how does the electrical field change if the paraffin
paper between the I and III layers is removed without changing
the length R?
