Electrostatic Potential The work done in moving a test charge from one point to another in a region of electric field: a b q 28 Electrostatic Potential In evaluating line integrals, it is customary to take the dl in the direction of increasing coordinate value so that the manner in which th...
Conduction Electrons and Holes An intrinsic (pure) silicon crystal at room temperature has sufficient heat energy for some valence electrons to jump the gap from the valence band into the conduction band, which become free electrons When an electron jumps to the conduction band, a vacancy is left...

the collapsing magnetic field produces a large voltage - briefly making the coil try to supply power back to the rest of the circuit This called a Back Electromotive Force (EMF) Application: Ignition coils in automobile engines to fire the spark plugs (Ouch - Don’t touch!!) It can damage...
Robotics Electric Watch Advantage of PM Motors They have a low power requirements due to presence of permanent magnet in the rotor. Due to use of permanent magnet the rotor has high detent torque. Drawbacks of PM Motors Due to use of large permanent magnet the motor gives a poor torque per...
Connection between Mechanics and Electromagnetism Why the validity of classical mechanics hinges upon the velocity of light ? Because light plays a basic role in the measurements of space and time that underlie mechanics. By critically examining the procedures used to measure length and time interval,...
3.1. Ab Initio The exponential growth of computational power has been the key driving force that Sensors 2020, 20, 974 10 of 23 electromagnetism are often used. We refer the reader to more specific examples on the topic, as provided in reference [48]. 3.1. Ab Initio The exponential growth...
