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 alkenes, with a single double bond and no other functional groups, known as mono-ene, form a homologous series of hydrocarbons of the general formula CnH2n. … Read more

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 both. This distinguishes FETs from bipolar devices in which both holes and electrons are responsible for the current flow in any device. Bipolar Transistor (BJT) … Read more

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 or electrically controlled resistors. The JFET operation can be compared to that of a garden pipe. The flow of water through a pipe can be … Read more

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 ability to change the conductivity with the amount of applied voltage can be used to amplify or switch the electronic signals. A semiconductor metal-insulated transistor … Read more
