Soldering:Soldering is a process in which two or more metal items are joined together by melting and flowing a filler metal into the joint, the filler metal having a relatively low melting point. Soft soldering is characterized by the melting point of the filler metal, which is below...
A digital multimeter is one the most versatile and useful instruments in your auto shop. It is important to own a good model and understand how to use it properly. A digital multimeter is actually three devices in one. It is a voltmeter that measure electrical potential across a device...
A bipolar (junction) transistor (BJT) is a three-terminal electronic device constructed of doped semiconductor material and may be used in amplifying or switching applications.Bipolar transistors are so named because their operation involves both electrons and holes. Charge flow in a...
A Zener diode is a type of diode that permits current not only in the forward direction likea normal diode, but also in the reverse direction if the voltage is larger than the breakdownvoltage known as "Zener kneevoltage" or "Zener voltage"....
Logic GatesLogic Gate:-"Logic gate is an electronic circuit which operates on one or more input signals to perform a particular logical function and produce the perfect output"Logic gates process signals which represent true or false. Normally the positive supply voltage +Vs represent...
BCD codeThe BCD code is represented using binary digits consisting of four bits.8421 code is a type of BCD and is composed of four bits representing thedecimal digits 0-9.8421 indicates the binary weight of 4bits.(i.e) two to thepower 3, two to the power 2, two to the power 1 and two...
