For time varying fields, the electric field is not conservative. Why? Explain with [3] mathematical substantiations.
Boundary conditions of Time-varying electric fields between two media.
An inductor a. passes direct current and opposes time varying current. b. passes time varying current and stops direct current. c. allows only magnetic field to go through it and stops any current through the coil. d. passes current whether it is time varying or direct. e. expels magnetic field through it. f. rotates if current is passed through it. Per Maxwell's first and second equations, an electromagnetic wave a. must have electric and magnetic fields perpendicular to the direction...

Electric fields and potentials a-d. Questions: a. Do any field lines cross one another? Why, or why not? b. Do any equipotentials cross one another? Why, or why not? c. At what angle do the equipotentials intersect the edge of the conduction paper? Why? Hint: The flow of electric current at any point is parallel to and directly proportional to the electric field vector. d. Where is the field the strongest? We were unable to transcribe this image
HELP with E-FIELDS.. please fully explain bc this question confuses me ___________________ 3. The electric field and magnetic field components of a signal propagating in free space are given by E(z,t)-nHo cos(7.5x10 t-Bz)a H(z,t)- H,cos(7.5x10't-Bz)a, Find the values of β and η such that these expressions satisfy all of Maxwell's equations.

Electric Fields -Prelab Name ate:n 3 2014 Lab day & time:.00p Question: What do the electric fields produced by charged conductors look like? Part P -1: In this lab you will be investigating the nature of the electric field. You will be using an electric field mapping aparatus in this laboratory. Here we will ask you to make a few predictions based on what you know at this time about what you expect. You will be asked later to comment....
