Very very very thank you my friend..... for your help
I have some questions below regarding the circuit above......... so please..... answer...
1)What is the value of R4 & R3 and R2 & R1, is it in ohms , kilo ohms or mega ohms !
All the values are Ohms.
NOTE: R1 R2 are just dummy loads for a 200mA test ONLY, you do not fit them.!
2)What is the use of R4 & R3 and R2 & R1 !
R3 and R4 are used to drop the voltage inputs to the regulators, in order to reduce the heat generated in them.
3)Is is using full wave rectification or half wave rectification !
Full Wave
4)Will the center wire of transformer will be common ground ! (You can see at my images of the transformer above , the secondary winding has two green color wire and one red color wire in middle).
The centre tap of the secondary winding is connected to 0V
5)How can we reduce or increase the output current !
The load you connect to the regulator outputs will determine the current!
6)Will the 12v output can drive 12v relay (Relay needs 60ma to work properly on 12v).
Yes.
7)What is the advantage and disadvantage of this PSU !
Work that out for yourself.
