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, when light strikes the cell, a particular portion of it is absorbed within the semiconductor material.
An alternating voltage is triangular in shape, rising at a constant rate to a maximumof 300V in 8ms and then falling to zero at a constant rate in 4ms. The negative half cycle
1 Farad: One farad is described as the capacity of that capacitor which keeps a charge of 1 coulumb, if the potential difference among the plates is one volt. It's equation
Q. Collector current I c =20 mA and base current I b = 50 A. Find current gain β of a transistor. β = I C / I B = 20 X 10 -3 / 50 X 10 -6 = 400
Positive rays are sometimes called as the canal waves. These were found by Goldstein. If the cathode of a discharged tube has holes in it and the pressure of the gas is around 10-3
