of an electrical device but in this a primary cell‚ that supplies current. What is a Cathode? A cathode is the positively charged electrode of an electrical device which in this case is a primary cell‚ that supplies current. What is Current? A flow of current which results from the ordered directional movement of electrically charged particles. A current is the rate of flow of charge. What is Electrolyte? The electrolyte in a cell is a chemical medium that allows the flow of electrical charge

Literature Search Both Design 2 and Design 3 circuits uses the concept of voltage doubler rectifier in particular the Greinacher voltage doubler rectifier‚ where the components used are mainly capacitors‚ diodes. Light emitting diode (LED) and 3-turn coil are also incorporated into Design 2 and Design 3 circuits. There are two main reasons of using a voltage doubler rectifier. Firstly‚ the LED require a forward voltage of 1.7V to 2.2V‚ and the 3-turns coil on the implant will not be able to pick

distribution as not only did DC work well with incandescent lamps (the principal load of the day)‚ but DC systems could be directly used with storage batteries‚ providing valuable load-levelling and backup power during interruptions of generator operation. Also‚ Direct current generators could be easily paralleled‚ allowing economic operation by using smaller machines during periods of light load and improving reliability‚ and Edison had invented a meter to allow customers to be billed for energy proportional

A tone generator sends a signal done the cable you use the probe that when it is touched to the correct wire will emit a tone that lets you know you have the right one. A tone generator will allow you to find shorts in the wires‚ mis-wiring and open wires. They are very time consuming to use and it is easier and faster to use a wire mapping tool rather than a tone generator. I believe that every installation kit should include a wire mapping

Conductors and Insulators of Electricity A major reason electricity works is because of conductors. First metal‚ water‚ tall trees and tall items are good conductors because lightning is attracted to them. These materials have many mobile electrons. Metal is an easy substance for lightning to travel through so metals are good conductors. However‚ rubber is a bad conductor because lightning bounces off of it. A bad conductor is called an insulator. An insulator has a few mobile electrons. It is
