Suppose the output of the op-amp is 15V. What must the voltage at the noninverting input be if R2=1kohm and R1= 9 kohm .
Suppose the output of the op-amp is 15V. What must the voltage at the noninverting input be if R2=1kohm and R1= 9 kohm . Then, what must be the voltage at the inverting input to invert the output to -15V?
