  Share On those days of navy-blue shorts, some are in love because of both having Apsara pencil, Pokey Man Bag, Ben Ten Exam Board, same colored sharpener, getting corrected answer paper very next to your girl or boy, keeping your copy with her copy in a bundle to be corrected and many more similarities. Yes, those are what we did find a girl or boy in school days because of. Some are more authentic so as had punished together for not writing the homework or imposition either. Some boys still remember the page number in English Text Book in which we had the word Love. Some boys may give a pencil to a girl without asking it back or for alternate. Because they do not had wanted it back. This is kind of attitude exactly similar to the paying bill in the restaurant. We are grown up but still we do not pay for others. We never choose a product unless sorting lowest price first. We are not penny-pinchers but still want to remain as thrifty at least up to finding a job. H...

What is Power Factor Correction? Power factor correction (also known as PFC or Power Factor Improvement) is defined as a technique used to improve the power factor of AC circuits by reducing the reactive power present in the circuit. Power factor correction techniques aim to increase the efficiency of the circuit and reduce the current drawn by the load. Generally, capacitors and synchronous motors are used in circuits to reduce the inductive elements (and hence the reactive power). These techniques are not used to increase the amount of true power, only to decrease the apparent power. In other words, it reduces the phase shift between voltage and current. So, it tries to keep the power factor near to the unity. The most economical value of the power factor is between 0.9 to 0.95. Now the question arises, why the economical value of the power factor is 0.95 instead of the unity power factor? Is there any disadvantage of the unity power factor? NO . There is not a single disadvantage ...
