(a) Find an expression for the voltage gain vO = vS in given Figure.
(b) Let RS = 1kΩ, RL = 1kΩ, and μ = 200. Find the voltage gain vO=vS as a function of RF. Find the voltage gain for three values of RF: ∞, 0 Ω, and 1 kΩ.
(c) Simulate the circuit in Multisim and perform a parameter sweep on RF from 10 Ω to 10 MΩ. Use the cursorto find your output at RF = 1kΩ. How does your answer compare with part (b)?
Suppose you are given two bars, one is anelectric dipole and the other is a magnetic dipole. Can you think of some simple experiments that would help you figure out which is which using a battery or a balloon?
