Specifications of bipolar junction transistor (BJT)

There are some important specification of bipolar junction transistor (BJT) are as given below, The bipolar junction transistor (BJT) has small signal current gain, α (hfb). Maximum collector current Ic (max). Maximum collector to emitter voltage, VCE

Advantages and disadvantages of air core inductors

There are some advantages of air core inductors are given below, The air core inductor is simple in construction. The air core inductor does not depend upon the value of current it carries and also eliminates the

What is BJT (Bipolar junction transistor)?

BJT (Bipolar junction transistor) is also called as transistor. Its amplify the weak signal. Basically the bipolar junction transistor is a semiconductor device it constructed with three doped semiconductor regions i.e. base, emitter and collector. The current

Improve quality assurance of electrical insulation in the factory

The latest partial discharge measurement techniques, explored in a CWIEME Berlin seminar, improve quality assurance of electrical insulation in the factory and prevent unnecessary costly repairs or outages in the field. Subject to high mechanical forces and

Conventional vs Non-conventional energy source

Conventional energy source Non-conventional energy source These are conveniently used everywhere for many purpose. These are not convenient to use everywhere due to some problems. These may be non-renewable sources. These are renewable sources energy. Its use

Voltage comparator and Schmitt trigger

Following are the Difference between Voltage comparator and Schmitt trigger. Voltage Comparator Schmitt Trigger Voltage Comparator has only one reference voltage. It has two reference voltage utp and VLlt. The input voltage applied to the non-inverting input

Types of induction motor

An Induction Motor is consist of two main parts which as follows – 1. Stator 2. Rotor The stationary frame called ‘stator’ and rotary part is called as ‘rotor’. The figure shown that construction of induction motor.

Difference squirrel cage rotor and wound or slip cage rotor

Squirrel cage rotor Wound or slip cage rotor This rotor is in the form of bars which are shorted at the end with the help of end rings. This rotor is in the form of 3 phase
