A capillary tube shaped conductor (silindirik boru) with p resistivity has length d and its dimensions shown in figure. Apply a potential difference Vo is applied between to ends. Show clearly which end positive and negative. a) Show the direction of electric field, current, current density in the conductor. b) Calculate the current density J in the wire c) Calculate the magnetic field everywhere. Show and explain every step by using Ampere's Law.
