1. The problem statement, all variables and given/known data Calculate the out put voltsge on the amplifier with a voltage supply of Vs 100 mV and Rs = 1k , R1=1k R2=10k. power comes from a +-15 v supply 2. Relevant equations V1-V2/r1+V1-V2/R2=0 V+=V- 3. The attempt at a solution it is the Risistor Rs that i am have trouble with since V+=V- on an op amp if i can find V+ then i think it can be done.
