Consider a square cross-sectional coaxial cable with an inner seaure conductor with side length a and an outer conductoe with side length b. A dielectric with relative permittivity &, fills the space between the conductors. If a DC source is connected to this cable such that the inner conductor has a potential of Vo volts, and the outer conductor has a potential of 0 volts, determine the potential everywhere between the conductors. a. Find an analystical expression for the salar potential and electric field between the conductors. Plot the field for a=0.2m, b=1m and Vo-1V.
