Hi Everyone,

I want a circuit which converts 0-10V to 0-5V using LM324.

I am trying to simulate the circuit in proteus using 2k and 1k(feedback) resistors and supply voltage is 12V.

But the circuit is not working.
 

You must show us your schematic. The easiest way is to use two equal value resistors directly across the 0-10V signal. At their center it will be 0-5V and no op-amp is needed.

Here I have attached my circuit image
 

This scheme have 1.5 gain not 0.5. Anyway, for scaling voltage by 0.5, as was mentioned, it's much easy to use a voltage divider. For what reason you choose an OP AMP?
 

IF the DC conditions were correct it would give a gain of 1.5.
What you want is an attenuation of 2 times (= gain 0.5). If you want to use an op-amp, connect two 10K resistors in series across the input and ground and from their junction connect the op-amp as a unity gain buffer. Connect the input to the + amp input and link the - input directly to the output pin.

Brian.
