a) Sketch the small-signal equivalent circuit for a field-effect transistor (FET) and explain how it can be deduced from the properties of the real device.
b) Draw the circuit diagram for a common-source FET ac amplifier based on a voltage-divider bias scheme.
c) Draw the ac equivalent circuit for the above amplifier.
d) If the transconductance of the FET used in a common-source amplifier is 3.4 x 10-3 S and the load resistance is 4.7 kΩ, what is the approximate voltage gain of the amplifier?

A radioactive substance has a half life of 1 min. If one nuclei decays now , when will be next decay????
if CPH has mass, so CPH Theory is able explain the universe future. Universe should collapse. And it is able explain dark matter too. Am I wrong? Answer; you are correct that C
Calorimetry is the act of calculating the heat of chemical reactions or physical changes, or the science of making such measurements. Calorimetry is performed with a calorimeter. T
An experiment was carried out to measure forces acting in two members of a pin-jointed framework due to different applied loading conditions. Dial gages P and Q were calibrated and
