Electrostatic precipitator

Hii,
All the engineers out there who work in thermal power plants must have heard about this term.ESP is a device located at smoke stack or chimneys to collect dust particles before releasing the smoke to air.As the dust particles can be harmful for people when they inhale the smoke so all the modern day thermal power plants use electrostatic precipitator.It consists of two electrodes,positive and negative.The dust particles while passing through these electrodes get attracted towards negative side which are then attracted towards positive electrode.It acts as an filter to remove the dust particles.
Thanks...

Sci-fi WH

Hey all, Consider two points A and B separated at a distance of say 5 cm in a piece of paper. If you were to reach point B from A you need to cover 5cm distance. But what if you wrap the paper in such a way that point A and B intersect. Then it becomes a shortcut right. This is exactly the concept behind worm holes. Due to the fabric nature of space-time this can be assumed that we can enter from past to future and vice versa through these holes known as worm holes created due to rupture in space time fabric due to movement of celestial bodies including planets. Time is a man made straight dimension but in our universe time is not moving forward rather everything is happening at the moment. It is like a 3hrs Bollywood movie being watched in a DVD where the time period for movie or event is fixed and we can go backwards and forward. Similarly events occuring in universe are fixed and we can rewind or move ahead using worm holes. This concept is hypothetical based on journals ...

Resonant frequency

Hello physics lovers, All of you must have heard the word resonance once in high school physics books.If not then today you would know.Well we all know that any object having swinging motion will have a frequency associated with it.Not only swinging object but any sort of vibration or sound will have frequency.This means frequency can be Mechanical,accoustical etc.so frequency is nothing but number of oscillations made in a particular time,si unit Hertz.Now what happens is that when the external frequency applied on an object matches with natural frequency of that object it vibrates with maximum amplitude.It can be catastrophic in practical situations.This is the reason why a troop of army personnel having March on a bridge are said to walk abruptly without matching the March of other members.This is because if the frequency of the army personnel matches with the natural frequency of bridge it would collapse.You would be astonished to know while traveling if your heartbeat matches wi...

What happens when you leave your charger on after your phone is charged completely?

Hey guys, It's very common that we forget to switch off the main supply when our phone is charged.We leave it on.Now the question is whether there is any power consumption.Theoritically if there is no load there should be no power consumption.But still the charger consumes very minimum amount of energy because the primary winding of the transformer consumes electricity and this is the reason why the charger gets heated after some time.So if this thing happens for few times it's ok but if it is kept on for larger period of time then power consumed is considerable.So make it a habit to turn the mains off once your phone or laptop is charged up. Thanks...
