Question 3 7 marks A coaxial cable is made up of two conductors one which has an inner radius of 1 5 cm and one which has an outer radius 5 cm The length of the cable is 200 m A potential difference of 3 kV is maintained between the conductors a Use the analogy between the D and J fields to calculate the current through the medium medium which is characterised by 1 8 and 10 S m b Calculate the power dissipated in the medium
