(a) Find an expression for the voltage gain vO/vS in Figure P4–10.

(b) Let RS¼10 kV, RL¼10 kV and m¼100. Find the voltage gain vO/vS as a function of RF. What is the voltage gain when RF is an open circuit, a short circuit, and for RF¼100 V?

(c) Simulate the circuit in OrCADby varying RF from 1V to 10 MV. Read your output RF ¼100 V. How does your answer compare with part (b)?
