Question
Chapter 54, Problem 1RQ
To determine
The polarity of the output from the operational amplifier.
Expert Solution & Answer
Explanation of Solution
The polarity of the input for Inverting pin changes at the output. For suppose if negative input is given, the polarity at the output will be positive. The polarity for the input given in non-inverting pin doesn’t change at the output as well.
When the voltage connected to the inverting is more positive, the output from the pin will be more negative. Thus irrespective of the input at the non-inverting pin, the net output from the op amp will be negative.
Thus, the polarity of the output from the operational amplifier is negative.
