Hello,
I have been trying to figure out how to work out the voltage highlighted in the picture. I have tried all sorts of of methods to analyse this. Standard voltage divider doesnt work because of the 24v and 12v paths, and I just can't get to 8.83v.I know it probably a very simple solution.
This circuit is part of a 741 op amp temperature measuring circuit which I'm designing. The resistances are just placeholders to help me work things out. The section of the circuit in the picture is intended to provide an offset so that the output of the op amp is 0-10v between the temperatures of 0 and 100 degrees C.
I'm not looking for an answer because I enjoy the satisfaction working these things out for myself, not to mention it's easier to remember that way. A little guidance would be very helpful though.I'm hoping to arrive at a formula so that I can use it in an excel spreadsheet that I'm using to simulate the circuit, so that I can test different values.
Any guidance will be much appreciated,
Thanks.
