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?
As we know photon's spin is one, how lots CPH (that have spin) is able keep the spin of photon? Answer; the photon spin like electron spin comes up of its properties and indepe
project work
How a CPH does stop or its speed decreases? Answer; it is a principle that Vc is stable thus that; gradV c =0 Thus, never V c increases or decreases.
The length of a simple pendulum is about 100cm known to have a accuracy of 1mm.Its period of oscillation is 2s determined by measuring the time for 100oscillations using a clock of

Spectrum and electromagnetic radiations: What is a spectrum? Ans: A spectrum is a group of wave lengths or frequencies. What are the electromagnetic radiations? Ans:
(i) X-rays are electromagnetic waves with wavelength lie among 0.1Å - 100Å. (ii) X-rays is invisible. (iii) They always go in a straight line with speed of light. (iv) X
