HI,
I'VE A DOUBT. PLZ LOOK THIS IMAGE AND MARK WHERE THESE POINTS(A,B,C) CONNECTED IN THE POT. PLZ.

Potentiometer

The center connection is the wiper contact to the carbon or other resistive materials track.
Both outer connections are the track the wiper travels across.

Your diagram with notations might be part of a circuit, so labeled for that circuit.
The link below might help.

HI,
YOU ARE RIGHT DAVE, THAT IS FROM AN AUDIO LEVEL METER CIRCUIT. THE IC NO. IS 3915. I'LL GIVE THE CIRCUIT TOMORROW.

Just trivia:
There are linear pots, constant resistance across the carbon track, and
Audio pots, which have logrithmic resistance.

Yes trivia, but if you don't understand, and are learning the basics, helpful.
Dave. :)
PS, To trivia for an answer ?

Hi,
plz tell me how to connect this stuff. that means A goes to input of the pot and b goes to output of the pot . because i'm a noobie.

Hook the wiper to one side of the pot and then put the pot in the circuit in the correct orientation. It really is that simple, what are you not getting?

edit: in the case of your logarithmic pot. Out hooks to in on the positive side of the circuit and ground hooks to ground. They are trying to tell you something, which side of the pot has the larger resistance since it is not linear. I might be wrong, but I think in the case of a volume control, the wiper wouldn't connect to either side of the track.
