Capicitor Application Issues
Capacitors must be built to tolerate voltages and currents in excess of their ratings according to standards. The applicable standard for power capacitors is IEEE Std 18-2002, IEEE Standard for Shunt Power Capacitors.

DC Generator 1
An electrical generator is a machine which converts mechanical energy (or power) into electrical energy (or power).
DC Motor
Electric motors are devices that convert electrical energy into kinetic energy of rotation, by the flow of electric currents through magnetic fields.The principle that a current flowing through a conductor which is placed in a magnetic field results in a mechanical effect, that is the conductor experiences a force, is exploited in electric motors.DC motors are everywhere! In a house, almost every mechanical movement that you see around you is caused by an DC (direct current) motor.
Basics of DC Machines
A machine manages power and performs or assists in the performance of ahuman task to accomplish. examples include, a mechanical system, a computing system, an electronic system. etc a molecular machine and abiological machine.
