Reluctance MotorBefore explaining about the motor let me clear you what is reluctance. Reluctance:It is the opposition offer to the magnetic force analogy to resistance in electrical circuit. It is the opposition to the flow of magnetic flux.Reluctance is the ratio of the Magnetomotive Force to the Magnetic Flux . The SI unit of...

Four Types Of  Distribution Feeders Systems:Radical Parallel FeedersRing MainMeshed Radical :Radical is the simplest and least expensive to construct. This is used when the generating station is at the center and different feeder radiate to the different direction and power flow is only in one direction.So, it has one feeder...

Transistors In 1947,The world of electronic devices is completely changed by the two physicistsJohn Bardeen and Walter Brattain when they made the first working device on point contact transistor.Transistor are the semiconductor ...

Earthing:Earthing means connection of the non current carrying part of electrical equipment to the Earth. Advantage:During fault condition if current flows through the equipment's, the chances of getting shock to the electrician will...

 Power FactorPower factor is normally the phase difference between the voltage and current. Power factor is due to the inductive nature of the circuit, however, in resistor the voltage and current are in phase with each other. So, the power factor of the resistive load is unity and reactive power is zero. All the power is active power...
