How do you test a transistor?
Connect the marked terminal as positive, first to the collector and measure the resistance. Then take it to the transmitter. In both cases, the counter must deviate (indicate open circuit…
Category: How to Guide
This category cover topics of electronics “How to Guide”. Basic theory of electronics and question answer with how tech works with easy way with example. it also cover electrical fundamental like current, voltage and its calculation, some circuit design, device use and benefits etc.
How do you test a diode?
Set up the multimeter to measure AC or DC voltage as needed. Turn the dial to the resistance mode (Ω). It may share a space on the dial with another…
Which way does a diode go?
Think of a diode as a one-way street for electricity. When the diode is in the feed direction, the diode allows circulation or current from the anode to the cathode…
How does a chiral column work?
Chromatographic column chromatography is a variant of column chromatography in which the stationary phase contains a single enantiomer of a chiral compound rather than an achiral. … As with all…
How do you separate two enantiomers?
The separation of a raceme in its components, pure enantiomers, is called chiral resolution. There are various methods, including crystallization, chromatography and the use of enzymes. To effectively differentiate both…
What are the different types of isomers?
STRUCTURAL ISOMERISM The isomers can be divided into two large groups: structural (or constitutional) isomers and stereoisomers. We will first consider the structural isomers, which can be divided again into…
Do alkynes have cis trans isomers?
In organic chemistry, an alkyne is an unsaturated hydrocarbon containing at least one carbon-carbon double bond. Alchemy and olefin are often used interchangeably (see the nomenclature section below). The acyclic…
Is FET unipolar or bipolar?
All FETs can be called UNIPOLAR devices, because charging carriers carrying the current through the device are all of the same type, that is, either holes or electrons, but not…
Why the JFET is called a voltage control device?
Junction gate field effect transistor (JFET or JUGFET) is the simplest type of field effect transistor. These are three-terminal semiconductor devices that can be used as electronically controlled switches, amplifiers…
Why FET is preferred over transistor?
The metal semiconductor metal-effect transistor (MOSFET, MOS-FET or MOS FET) is a field-effect transistor type (FET). It has an isolated gate whose voltage determines the conductivity of the device. This…
