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?
There are five types of modulus of elasticity (i) YOUNG'S MODULUS OF ELASTICITY (Y (ii) BULK MODULUS OF ELASTICITY (K) (iii) COMPRESSIBILITY (iv) MODULUS OF RIGIDITY

MOTION: A body is said to be in motion if it alters its position with respect to its surroundings.
Determine divergence of a position vector?
Radioactive Decay Series The sequential decay of a given nucleus results in the production of a series of nuclei or elements. This series of elements thus formed is known as a
The weight of a body is the force with which it is attracted in the direction of the centre of earth. When an object is stationary with respect to the planet, its weight equivalent
