Answer Posted / dileep
currents are two types 1).conventional current
2).directional current
if u take a semi conductors then current is due
to both of electrons and holes .electrons will flow towards
+ve terminal battery supply,in case of holes flows to -ve
terminal conventional current .in case of diodes arrow head
shows that conventional current i.e opposite to electron
current so in semiconconductors u are correct
but in case of metals current is due to
electrons only holes will not exit .direction of current is
same as voltage polarity

Why do we apply both Differential and REF (HV and LV) protection schemes on YNyn configuration of a transformer?
In case of salient pole alternator when number of poles are 4 or more than 4 it helps the flux wave to be sinusoid as air gap length is increased from center to tip , but if the number of poles are 2 how does the flux wave is sinusoidal?
A commercial Building is designed with 14th floor levels with indoor substation of three phase transformer with rated capacity of 1000 Kva.The transformer delivered 65% of its rated capacity at 0.67 power factor lagging.Because of low power factor, the power customer was penalized and certain cost was charged accordingly based on every point percentage lower than 85%.This situation may repeatedly happen on the succeding energy bills of power customer.The power customer is desired to improve its historical power factor of 0.67 lagging and no further penalty be impose by the local power company on the next bill.

Can u explain : what is supply for train (whether a,c or d.c ).I know that supply is 25000v a.c .But there is rumour that supply is D.C. And also explain how lights and fans inside the trains are working ,and what type of motors are used in trains whether D.C motors or induction motors .If d.c motor, how it gets supply.If traction motors are used then what are traction motors and its functions and how it differs from other motors and also explain about locomotive . y d.c series motor in train.train wheels r driven by D.C shunt motor ,at what voltage,and at what speed. please reply..............
