Number of holes in valence band:
Derive the expression for number of holes in valence band and Fermi level in an intrinsic semiconductor.
(b) By that percentage does the conductivity of intrinsic Ge at room temperature increase per degree rise in temperature ?
Sol. (b) We know that at room temperature when temperature is increased by 10, then conductivity goes to double. i.e. with 10 increment in temperature, conductivity will be = 100% with 1 increment in temperature, conductivity will be = 10%
A three-phase, six-pole, wye-connected synchronous generator is rated at 550 V and has a synchronous reactance Xs = 2 . When the generator supplies 50 kVA at rated voltage and a p
Give some applications of constantan. Constantan is an alloy of nickel and copper. It is used in thermocouples, motor starters and precision resistors.
