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?
Definition of semiconductors Photovoltaic (PV) cells are made of special materials known as semiconductors like as silicon, which is currently the most commonly used. Basically

"The volume of needed mass of gas at fixed pressure is directly proportional to the Kelvin's temperature of the gas".
Determine the Charge of the lithium ion A mass spectrometer often is used in carbon dating to verify the ratio of C-14 isotopes to C-12 isotopes in a biological sample. This ra
when told that a diffraction grating has 80 lines per mm we need to work out what 1 line would equal. I have the solution but i cannot figure out how they got 1 line to equal 1x10
