Thermal Or Steam Power Plants are those power plants that run on steam. In thermal power station fuel is burn and the is used to convert water into steam

To build a controlled rectifier or a phase-controlled rectifier,the diodes in the rectifier circuits are replaced by SCR. These circuits produce variable DC o/p

To obtain satisfactory and reliable SCR operation, it is necessary to provide protection against over voltages and over currents.

For proper operation of circuits using SCRs, the trigger circuits should supply the firing signal at precisely the correct

If an SCR is forward-biased and a gate signal is applied, the device turns on. However, once the anode current IA is above the holding current,

MCT (MOS-Controlled Thyristor) and SCS (Silicon Controlled Switch) are the low power devices belong to Thyristor family.

Three types of rays emits continuously from a radium material. These rays are known as alpha rays (a rays), Beta rays (p rays) and gamma rays (x rays).

The frequencies which are beyond the limit of hearing are called ultrasonic. The ultrasonic waves are of frequencies above 20000Hz (20 KHz).

The term UJT stands for Uni Junction Transistor. This type of transistor possesses one PN junction and three terminals. Construction, working, applications

In electronics timers the output of the timing element is used as a trigger pulse for BJT, FET and UJT, the active devices element signal
