Hi I am Arup..I would require details about the project battery eliminator...please!!!! Make the project available here...please!!!!

Battery Elementator Physics Project
Battery aliminator is a device used to convert high voltage at current low voltage direct current. A circuit arrangement is employed, with 220 volts rotating, the current 4½ volts are converted into direct current. With the help of this device, the use of the battery has expired, so it is known as the battery extractor. It has the following parts:


Transformers:

Transformer device used to convert low-voltage high-voltage turn current to low current or low voltage current to convert smaller reversible streams at high voltage in turn. In our project, step-down transformer is used.

RECTIFIER:

The pure current device is used to convert to current current. There are two types of purifying

(i) half-wave purifier

(ii) Full wave purifier

The complete wave purifier is used in our project which changes the entire wave of the current state of the whole wave of direct current.

Transformer

Transformers:

Transformer is a tool used to convert a low turn voltage into a low turn voltage or a low turn voltage of a high turn voltage.



theory:

It is based on the principle of mutual induction, if a different current circuit-driven e.m.f. Has been established in A circuit is produced in the neighboring circuit, there is a different magnetic flow that is different in the circuit, which is different from the e.m.f. Inspires. In the neighboring circuit

step down transformer :

Down Transformer is used in our project:

This transformer currently converts low-voltage current into high voltage alternating current. In the step-down transformer, the number of turns in the primary coil remains large, which is higher than the secondary coil.
