Difference between conductor, insulator and semiconductor

Conductor Insulator Semiconductor The conductivity of conductor is very high. The conductivity of insulator is very low. The conductivity of semiconductor is moderate. It has very low resistivity. It has very high resistivity. It has moderate resistivity.

Difference RC phase shift oscillator & Wein bridge oscillator

RC phase shift oscillator Wein bridge oscillator This oscillator is used for low frequency range. This oscillator is used for low frequency range since both are RC oscillator. Feedback network provide 180° phase shift. Feedback network do

Basic Electrical Theorems and Circuits Analysis Laws

Application of IC 741

IC 741 is used in Amplifier. It is used in active filter. It is used in Arithmetic circuit. IC 741 is used in log and antilog amplifier. It is used in voltage comparator. It is used in

Pin diagram of IC 741

IC 741 Operational Amplifier (Op-amp) The operation amplifier (Op-amp) is basically voltage amplifier with extremely high voltage gain. Pin Diagram Symbol of IC 741 The Op–amp IC 741 has two input terminal, one output terminal and two

Advantages of rotating field and stationary armature system

In this case of high voltage generation, the instruction problem is server. If the armature is rotating, this is due to centrifugal states develop in the body due to the rotation. But if the armature is the

Working principle of Alternator

The work on the principle of Faraday’s law of electromagnetic induction whenever the conductor cuts the magnetic flux and emf in induced in it. This emf is dimensionally induced emf. The direction of emf is found by

Double Cage Induction Motor

In case of 3Ø squirrel cage motor has low starting torque. This is due to the low Rotor Resistance. Then, the starting torque with increase but at the same time their will be more copper loss and

How does a transformer work

Ideal Transformer Idea transformer is nothing but a transformer which has 100% efficiency. In this transformer there are two purely inductive coils. So this is no iron loss, no copper loss, as well as there is no

Difference between Ideal transformer and practical transformer

Concept of Ideal Transformer Idea transformer is nothing but a transformer which has 100% efficiency. In this transformer there are two purely inductive coils. So this is no iron loss, no copper loss, as well as there
