Problem 7.25 consider the fet amplifier below, for the case vt = 0.4v, kn = 5ma/v2, vgs = 0.6v, vdd = 1.8 v, and rd = 10 kω. a) find the dc quantities id and vds. b) calculate the value of gm at the bias point. c) calculate the value of the voltage gain.

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet
