The potential differance between two enclosed regions
This is for just number one of this problem set. Need a detailed solution so I can understand future problems of this type. Thanks
Capacitance with Permittivity (Laplace's Equation)
A parallel plate capacitor has its plates at x = o and x = d. The space between the plates is filled with an inhomogenous material with permittivity: {see attachment}. The plate at x = d is maintained at Vo whilte the plate at x = o is grounded. (a) Solve Laplace's Equation for V(x) (b) Find the field {see attachment} between ...continues
Ring of Current - Loop Antenna
I'm not too sure of how to go about proving a general solution for this. There is an attached image of the loop. I'm just learning about this and really need some guidance. Question: Derive an expression for the magnetic field intensity (vector H) on the axis of a loop of current I. The result should be a function of the c ...continues
