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?

Scientific principle behind a laser: The basic scientific principle behind a laser was first put forward by Dr. Charles H. Towns in 1954 which later led to the development
A charge q1 is 9.00um is at the origin, and a charge q2 is -4.00um is on the x- axis 0.30m from the origin. find the electric field strength at point P, which is on the y - axis 0.
The rate of change of angular velocity with related to time is known as angular acceleration.
