What Is EEPROM ? EEPROM is also called a non-volatile memory because when power is turned off the stored data in the EEPROM will not be erased or intact. New EEPROM have no data in it and usually have to program with a programmer before it can be use. Information stored in this type of memory can be retained for many years without a steady power supply.What is the function of EEPROM?EEPROMs are used to store user......

What Is A Fuse ? And How To Test It. Purpose of FusesThe purpose of a fuse is to open an electronic circuit when current flow exceeds a certain amount, determined by the rating of the fuse. Opening a circuit under high current conditions can save electronic components from damaged and prevents overheating, which could cause a fire.Types of FusesThere is two basic types of fuses: fast acting and slow blow. The fast acting type will...... Source : Study Technology

What Is ESR METER ? Why should I use an ESR?Because measuring an electrolytic capacitor with an analog or digital capacitance meter can MISLEAD a technician into believing that a defective capacitor is good. This can waste your precious time and you are unable to repair the equipment. Which means you cant charge your customer! If you dont test for ESR on the capacitor, you will always miss the bad capacitor....... Source : Study Technology
What Is A Crystal ? And How To Test It. Testing CrystalCrystals are quite fragile components because of their construction. Unlike a resistor or capacitor, if you drop one on the ground from a decent height, its 50-50 bet whether it will work again. Testing the crystal is not a breeze either. You cannot just take out your trusty multimeter and plug the crystal in it. In fact, there are three right ways to test a crystal: -(a) Using......
