A student is measuring the gain of the voltage follower a for different source and load conditions. First, with Rsig 5 0 and RL 5 300 V, the gain is found to be voyvsig 5 0.853 V/V. Next, inserting a resistance Rsig 5 10 kV while leaving RL 5 300 V, causes the gain to drop to 0.718 V/V. Based on the above measurements, can the student predict the gain with Rsig 5 20 kV and RL 5 1.2 kV? Hint: in fact, the student can even tell the values of 0 and IC!
