Hi everyone.
So need help finding the voltage diffrence between V1 and V2 where the voltages across a series of 4 3.7 voltage cells. So essentially If I am looking at the first cell, the voltage at V1 terminal of the op-amp is 14.8 = 3.7*4 and the voltage at v2=11.1=3.7*3. I want the output voltage to show me 3.7 Volts, but All I am getting is 11.1!
Also note, its a single source 15 volt supply.
Here is the multisim design I am working with.
Can Someone Please help!
[EDIT]
WOW, EPIC FAIL ON MY PART
I used A LM318 OP-AMP instead and I got it to give me a gain of 1.
All done, I just need to choose between a 741 or 318. I know 318 is much better, but will it be sufficient for my needs.
