Wound Rotor & Squirrel Cage Induction Motor Theory

Wound Rotor & Squirrel Cage Induction Motor Theory

Asynchronous machines are more known as induction motors because their principle of operation is based on induction. Recalling Faraday’s law, if a wire is moved in a magnetic field, then a voltage difference is generated between its two ends. We may also say a voltage or an electromotive force is induced …

Single-Phase Transformer | Construction | Theory

single phase transformer.

In the same way that single-phase AC and three-phase AC are different, although both are alternating current electricity, single-phase and three-phase transformers cannot be interchanged. Nevertheless, most of what can be said for single-phase transformers is later on extended to three-phase transformers because they work based on the same principle. …

Resonance in Series and Parallel RLC Circuit

rlc circuit resonance

In any AC circuit consisting of resistors, capacitors, and inductors, either in series or in parallel, a condition can happen in which the reactive power of the capacitors and of the inductors become equal. This condition is called resonance. Simultaneous with the capacitive reactive power and the inductive reactive power being …

Integrated Circuit (IC) | Construction, History & Types

integrated circuit definition

Definition: An integrated circuit, or IC, is a complete electronic circuit contained in one package, Figure 1. This package often includes transistors, diodes, resistors, and capacitors along with the connecting wiring and terminals. An IC is also called a chip. The transistor was invented in 1947 by Brattain, Bardeen, and …

Common Emitter Amplifier: Working & Circuit Diagram

Common Emitter Amplifier

Amplifier Definition: An amplifier is an electronic device that uses a small input signal (voltage or current) to control a larger output signal. This principle works best when the output load, or impedance, of the circuit, is greater than the input load. Examine Figure 1. The input is a microphone …
