Q. Which are the three basic configurations of FET amplifiers?
The three basic configurations of FET amplifiers are
· Common source(CS)- It is most frequently used as it provides good voltage amplification
· Common drain(CD) or source follower-It is used as a buffer amplifier. It has high input impedance and near unity voltage gain.
Q. Given ¯B = (y ¯ax - x ¯ay )/(x 2 + y 2 ) T, determine the magnetic force on the current element Id ¯l = 5 × 0.001¯a A located at (3,4,2).
