... A motor performance curve is a picture showing the relationship between inputs and outputs. Let's choose motor speed in revolutions per minute (RPM) as a reference point and look at torque. Torque is a measure of the force a motor can develope to turn something. Begin in the lower left corner of the ...

... They are all caused by static electricity. Static electricity is due to electric charge that builds up on the surface of an insulator. The charge that has built up cannot easily flow away from the insulator, which is why it is called static electricity. ...

Electric Fields and Potentials
... Many early books on electrical engineering are full of talk about the "density of lines.” Field lines and equipotentials are a useful way to think about what electric force will be exerted on a charged particle that is in the vicinity of other charges. Closely spaced field lines are associated with ...

... Consider a sphere of radius R and charge q. In the region outside the sphere it will generate an electric field that is that of a point charge q, located at the center of the sphere. The electrostatic potential in this region is thus also that of a point charge, and we thus conclude that the electro ...

... For a charge that is outside of a spherical shell it is also easy to prove that the total flux through the shell is zero. This is proven by noting all flux lines originate or terminate at a charge, or go to infinity. Therefore a flux line originating from a charge outside the spherical shell and whi ...
