INTRODUCTION
A full wave rectifier is a device which is used to rectify all the alternating current components in an alternating supply and make it purely a direct current. The two alternating halves of an alternation current are rectified in a full wave rectifier which is an advantage over a half wave rectifier. Most of electronic devices cannot withstand very high voltage or alternating current due to its intense high power. The use of batteries in all devices is not practical as their replacement and durability is a huge problem as the device has to be dismantled each time for such a replacement. So these rectifiers are used in most of the electronic devices like TV’s, Radios, Chargers and Lightings etc.
There are several stages in a

It is also called Semiconductor or crystal diode. When diffusion of the two regions occur a resultant potential barrier is created between the two sides due to migration of electrons and holes.
When the diode is connected with P side to positive terminal of a battery & N side to –ve terminal it is said to be forward biased & reverse biased when reversed. In forward biasing the applied positive potential repels the holes and turns a current is made to flow overcoming the internal potential Barrier. While in reverse biasing the –ve electrons 1st attract the holes and widen the Barrier and then only the repulsion between inner electrons occur and current flows. So theoretically no current flowsthrough due to the widening of the Potential barrier but practically a very small current does flows through. Different types of diodes are present :
1.Zener diode, 2.P-N junction diode, 3.Led , 4.Lad, 5.Solar Cell, Here we use a P-N junction diode. The greyish ring indicated the N side and the Black colouration the P side.
xii)Finally, small equipments such as a soldering iron to solder the lead, Blades, holders, insulation tapes – to insulate the wire from shocking and sand paper – to rub the oxidized wire ends are used.

The nichrome wire is silver with a sort of rusty brown color on portions of it and is not slightly shiny. When the nichrome wire was put into the heat (bunsen burner), the flame turned from blue to orange, and the wire began glowing orange in the part touching the flame. This was a physical change because the only thing that changed was the color was changed but went back to normal, thus indicating that the composition has not changed.
Insulator – Do not allow electric charges to pass through them. Electrons in the atoms and molecules move very slightly to one side of the object but are not released.
There is several pieces of PPE equipment that must be work whilst milling, equipment is as follows:

Looking further into batteries(most batteries) during the discharge of electricity, the chemical on the anode releases electrons to the negative terminal and ions into the electrolyte in a process called oxidation. The positive terminal accepts these electrons and thus completes the circuit making the flow of electrons. Between electrolyte solutions the ions move through the salt bridge to maintain electrical

When the lithium battery is charging, the positive electrode will give up some of the lithium ions it has, the lithium ions will make their way to the negative electrode through the electrolyte which is where they will remain. During this process the battery will gather and store energy. Whilst the lithium battery is discharging the lithium ions will pass backwards through the electrolyte to the positive electrode, this will then create the EMF that will power the battery. Whether the battery is charging and discharging the electrons will flow in the opposite direction to the ions around the circuit. The electrons cannot flow through the electrolyte as the electrolyte acts as a barrier or insulator to the flow of
