    im confused about the diode voltage drop...

    hmm..sorry a voltage supply is connected to the non inverting terminal

    this is an inverting voltage follower..so the cathode would be at negative potential...is it correct?

    http://en.wikipedia.org/wiki/File:Op-Amp_Precision_Rectifier.svg actually this is the circuit that i wanted to draw.

    by opamp output..you mean the terminal to which anode terminal of the diode is connected ..right?

    you mean the load voltage will be the negative of Vin

    but usually dont we write the output of the opamp at the feedback junction...i mean does it change?

    wow..thats a neat explanation..thanks...but i have one more small doubt...generally when we talk of opamps where is the output voltage( ie Vout=K(V+ -V-)) ...is it AT the feedback junction or BEFORE or AFTER it?
