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 charged particle is moving in a UNIFORM magnetic field. If the direction of motion of the charged particle is parallel to the magnetic field, explain the shape of the charg

Q. Name the types of photoelectric cells? The photo electric cells are of three kinds: A) Photo emissive cell B) Photo voltaic cell and C) Photo conductive cell.
Using a pulley Use the pulley set-up shown in experiment A 12. Apply the force on the movable pulley and get how rapidly the weight on the other end of the string rises.
what is the theory behind bernoullies theorem?
Dalton's law of partial pressures (J. Dalton) The overall pressure of a mixture of ideal gases is equivalent to the total of the partial pressures of its components; i.e., the
