All capacitors have a certain amount of resistance to the passage of AC current. ESR (Equivalent Series Resistance) is the sum of all internal resistances of a capacitor measured in Ohms...

# A fuse is a very thin wire, which either melts or vaporizes when too much current flows through it. The thin wire may be made of aluminum, tin-coated copper or nickel. The resulting open in the circuit stops current flow.

If, for some reason, you can't get an exact replacement for the transistor that you want to replace, you can refer to one of the transistor substitution guides or book, and try to identify a "near replacement". Beware, however...

Understand the procedure on how to set up a electronic repair authorized service center...Setting up from scratch as an Authorized Service Center is not an easy job. Your workshop needs to meet the manufacturers' requirement first

# Simple ways to understand about the functions of crystal and how to check it...

Easily and quickly understand the code number of picture tubes or crt...All picture tubes, whether monochrome or color type are identified by a specific code consisting of numbers and letters. The codes are different from each other because different tubes have different characteristics.

# Learn the simple ways to troubleshoot your own laser printer without sending to a laser printer repair center.

Understand the functions of EEPROM and how it fails... 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.

# Learn the simple and easy way to read zener diode code number. Many technicians are confused on how to really read a zener diode code. There are many types of code number indicated on its body.
