Solve the below:
Q: Consider the augmented hybrid-π model shown in Fig. Disregarding how biasing is to be done, what is the largest possible voltage gain available for a signal source connected directly to the base and a very-high-resistance load? Calculate the value of the maximum possible gain for VA =25 V and VA =125 V.
