How to make an INDUCTOR

My discussion here is very simple,unlike presenting u all the history like Wikipedia. and boring you with all its properties characteristics etc. i shall leave here a simple discussion which is very much needed practically when you work them.the main emphasis here is about HOW TO DESIGN AN INDUCTOR and its COLOR CODES!!!Sometimes you may be unable...

RELAYS

A relay is an electrically operated switch. Current flowing through the coil of the relay creates a magnetic field which attracts a lever and changes the switch contacts. The coil current can be on or off so relays have two switch positions and most have double throw (changeover) switch contacts as shown in the diagram. Relays allow one circuit to...

MAKE UR OWN SIMPLE COMPONENT TESTER

This simple project may be used for testing components, as well as checking circuit board tracks, wires and connections for continuity (conduction). It tries to pass a small current through the item being tested and the LED will light brightly, dimly or not at all according to the resistance of the item: LED bright means the resistance is low, less...

TRANSISTORS

Function Transistors amplify current, for example they can be used to amplify the small output current from a logic IC so that it can operate a lamp, relay or other high current device. In many circuits a resistor is used to convert the changing current to a changing voltage, so the transistor is being used to amplify voltage. A transistor may be...

SOLDERING GUIDE

How to Solder First a few safety precautions: Never touch the element or tip of the soldering iron.They are very hot (about 400�C) and will give you a nasty burn. Take great care to avoid touching the mains flex with the tip of the iron.The iron should have a heatproof flex for extra protection. An ordinary plastic flex will melt immediately if touched...

CAPACITORS

we are studying from our schooling what is a capacitor and its properties,so i dont want to bore you starting from its defination,the article here is just an update for your basic theoritical knowledge, There are many types of capacitor but they can be split into two groups, polarised and unpolarised. Each group has its own circuit symbol. Polarised...
