1. An abrupt Si p-n junction has Na = 1017 cm³ on the p side and Na = 1016 cm³ on then side. At 300 K, (a) calculate the Fermi levels, draw an equilibrium band diagram, and find Vo from the diagram.
In general, which of the following is/are a factor that will determine the synchronous speed of a 3-phase motor? 4. a) frequency b) number of stator poles per phase c) both "a" and "b" d) neither "a" nor "b"
Two 60MVA, alternators operate in parallel. The setting of the governor are such that the rise in speed from full load to no load is 2% in one machine and 3% in the other, the characteristics being straight lines in both cases. If each machine is fully loaded when the total load is 120MW, what will be the load on the first machine (with 2% speed regulation) when the total load is reduced to 80MW?
Q25)ii) When the speed difference will be maximum in three phase induction motor. Justify your answer
"During loss of prime mover, the alternator runs as synchronous motor " True False
What should be done to keep the alternator terminal voltage constant at different loads as the alternator is loaded?makes? Please explain
A three phase induction motor is wound for 4 poles and is supplied from 50Hz system. Calculate the synchronous speed and speed of the motor when slip is 4.1%
A three-phase 5012 induction motor has six poles. If the full load slip is 5%, determine the rotor speed. Av B 1
