The output voltage and the input voltage of the following circuit is to be proved to be related as
An explanation is also required as why the given circuit works as a voltage follower with gain.
The concept of virtual ground(short) is used based on which the voltage maintained at both the terminals is the same. From the given circuit the relation between the input and output voltage can be obtained using virtual short and potential divider concept. The output can then be proved observed to follow the input with a gain.
