    Ritesh,

    I think you'll find that if you show evidence that you have attempted to find these answers yourself you will have more luck with having some engaging feedback.

    Leon's google suggestion is a good place to start, if you search for example for "AC RMS PEAK AVERAGE", you will find a large number of links to information on the topic.

    Your request for what amounts to a "brain dump" without showing much effort on your part comes across as being somewhat disrespectful to the time and effort that more experienced people have put into gaining their level of knowledge.

    Respectfully,

    C.W.

    Hi, how to increase the current from 7812 iC as it maximum current is 1.5A with heat sink, but i want upto 3A,How??

    It's in the data sheet.

    Ritesh,

    You should start a new thread when you ask a question on a new topic.

    Anyway...once again our friend google comes to the rescue, google "7812 increase current", you will find many links with solutions to your question.

    Most of the solutions involve the use of a series pass transistor.

    It is always a good idea to search for a datasheet from the manuafacturer of the chip you plan to use, they often include application notes that are helpful in situations like this.

    The first link that google listed when I searched the above included a link to a Fairchild datasheet for the 7812, that would be a good resource for you.

    I'm trying to teach you to fish.

    C.W.

    That mean it is possible to increase the current of 7812 IC, more than 1.5A.

    Can we replace BD536 transistor by it equivalent??

    It depends on the transistor you use, of course.

    Please tell any other equivalent transistor for pumping 3A current??

    Your task is to look in a distributor's catalog, like Mouser or Jameco, for a similar transistor. It should be the same type. If you don't know the differences among the symbols for different kinds of transistors, look in the Wikipedia. You want to be able to tell the difference between a bipolar junction transistor and an MOSFET and between PNP and NPN polarities. When you try to replace a transistor, you normally look for one with the same or modestly higher current rating and voltage rating. You typically want one with the same or higher gain. For this application, the gain probably doesn't matter much. If you do a web search for the transistor's part number, you may be able to find a data sheet for it. You may even find some equivalent transistors from other manufacturers. You have to do some work after all.
