This question is related to electrostatics. As we can see from the figure below, we have got a rectangular bar A 3 m long rectangular bar made of 2 polymers bars with the same cross-sectional area S = 0.01 m2, lengths /1 = 2 m, 12 = 1 m, relative electric permittivity Er = 3, Ear = 2, and electric conductivities 01 = 2x10-8 S/m, 62 = 10-8 S/m. Details are shown potential V can be applied at the left edge of the bar and the right edge is grounded. es E, 62 area s The question is the following: At time instant t = 0 sec a potential of 400 V is applied at the left edge of the bar and the right edge is grounded. Find the electric field distribution and electric charge densities p1 , p2 at electrodes "1" and "2" at t = 0 sec
