### Lenz’s Law In Transformer | Electrical Machines | EE

Friday, 20 October 2017

Real Life Application It can be applied to Transformers to find out the instantaneous polarity of induced emf.   Explanation To understand the operation of Transformer with clarity it’s important to visualize the secondary induced emf and flux flow in the transformer core. Emf will be induced in any coil if the flux linkage changes

### Fleming’s Right Hand Rule Application | Electrical Machines | EE

Friday, 20 October 2017

Real Life Application It can be applied to any Electrical machine like DC generator, Induction motor, Synchronous generator.   Explanation To understand all the Electrical Machines with clarity it’s important to have basic idea of the relation between Electric Current and Magnetic Field Relations between Electric Current and Magnetic Field: A steady current produces a

### Pipelines | Computer Organisation and Architecture | CS

Friday, 20 October 2017

Explanation:             The pipelining is a technique of decomposing a sequential process into sub operations, with each sub process being executed in a special dedicated segment that operate concurrently with all the segments. A pipeline can be visualized a collection of processing segments through which binary information flows. The pipeline concept is organized into two

### Instantaneous centre of rotation | Engineering Mechanics | ME

Friday, 13 October 2017

The instantaneous center of velocity (IC) is a unique reference point which momentarily has a velocity of zero magnitude. Thus, as far as velocities are concerned, the body seems to rotate about the instantaneous center, that is, the velocity of any point on the rigid body is simply the angular velocity of the rigid body times

### MOS Capacitor | Electronics Device and Circuits | EC

Friday, 13 October 2017

Real Life Applications: MOS Capacitor is basically a two terminal MOSFET. Beauty of this capacitor is it will be generally used under equilibrium. All the Enhancement properties of MOSFETs are coming from MOS Capacitor. Why MOSCAP is important? In the GATE point of view, this topic is hot favourite of the GATE committee. In last

### Three Point Starter | Electrical Machines | EE

Friday, 13 October 2017

Real Life Application A Three point starter is used to start dc shunt motor or dc compound motor. Explanation To understand this we need to realize that high current will flow in dc motors at the time of starting, as the speed is zero and the back emf is zero and thus current is enormously

### Plastic Analysis | Steel Structures | CE

Friday, 13 October 2017

Real Life Applications: This method is also known as method of load factor design or ultimate load design. The strength of steel beyond the yield stress is fully utilized in this method. This method also provides striking economy as regards the weight of steel since the sections designed by this method are smaller in size

### Base Width Modulation | Electronics Device and Circuits | EC

Monday, 18 September 2017

Real Life Application: In active region BJT will act as amplifier and we have assumed that the current gain alpha and beta will be constants with respect to applied voltage, which will not be valid in practicality because as we will apply ac signal in input then voltage in the BJT will keep on changing.

### Basics of Synchronous Machine | Electrical Machines | EE

Monday, 18 September 2017

Real Life Application The primary supply of all the world’s electrical energy is generated in three phase synchronous generators using machines with power ratings up to 1500 MW or more. The ability to control power factor makes them an attractive choice. As Synchronous condenser: by varying excitation it can made to operate on lagging or

### Introduction to Heat Transfer | Heat Transfer | ME

Monday, 18 September 2017

Introduction to Heat Transfer This lecture is short description of the subject of heat transfer. It gives an idea of the scope of the subject, its applications and discusses a basic difference between the three mechanisms of heat transfer through examples. Scope: Heat Transfer vs. Thermodynamics Whenever a process occurs, it involves some kind of
