Short circuit voltage of a transformer mainly depend on
A ohmic resistance of primary B ohmic
resistance of secondary
C magnitude of leakage flux D cross
sectional area of core
Do any one know exacatly when the results for NHPC held on 8th march 09 for engineering trainees will be released ?. if so please post it, i'm eager to know it.
Wheather there exist any dc transformer
why we have and use 3 phase not 2 or 4 or other in power system?
what purpose of the percentage impendance in transformer
what is the effect of power factor in electrical circuit ? if we mainten power factor near about unity (0.999) our energy consumption Units increase or decrease?

why ac can not be stored?
In DC motor,the field MMF is given by NI.N-no.of field winding turns,I-excitation and both are constant.Then how could the main flux decreases due to armature reaction.
What makes the difference between 50Hz supply and 60Hz supply which one is economical? What is the use of using increased frequency?
What is transmittance?
how can we test the polarity of a 3-phase transformer?
Explain about retrofitting of machine tool.
In generation,transmission and distribution voltage frequency is either 50HZ or 60 HZ;why are only these frequencies?
