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) Distinguish among metals, insulators and semiconductors on the basis of their energy bands. (b) Why are photodiodes used preferably in reverse bias condition? A photodiode i
give example phenomena of resonance?
A) Explain the flow of direct current? ( describe direct current) b) Explain the effect of resistance in circuits? (Describe effect of resistance)

Sir i don''t know how to 36.25 solution
calculate the acceleratio due to gravity on planet mercury if mass = 2.99 x 10 9to the power 23)kg and radius = 2.42 x 10( to the power 6) metres.
In an isothermal process, the temperature of body always same throughout the process. As the internal energy of a system depends only on its temperature, thus there is no modificat
