Electrodynamics Problem 1 Twelve wires, each of resistance r, are connected to form the edges of a cube. Calculate the effective resistance R of this network across a body-diagonal of the cube. Electrodynamics Problem 2 Consider a capacitor connected to a battery of voltage V. Let the capacitor have an area A, and distance L between the plates. Assume that the capacitor has a layer of dielectric (of dielectric constant κ , so that o κε ε = ) of thickness L/2 on the lower plate, as shown in the figure. a) Calculate the capacitance of the capacitor. b) Calculate the charge on the capacitor. c) Calculate the value of the electric displacement D in the capacitor. d) Calculate the value of the electric field inside the dielectric layer, and in the air above it. e) Calculate the electrostatic energy stored in the system. How would it change if the dielectric is removed?
