respected sir,
sir recentely i have applied for chennai and
tiruvananthapur section enggineer and juniour engg in
electrical dept.
but still i donot get how i have to syart my preparation
and also t the same time i donot know exactly what they r
going to give in the examinations i mean which sections
they r going to give i donot know exactly, can u prefer
whichh books i have to follow and model papers or both
boards
If a shunt Dynamo has induced emf 100V and 0.4 ohm resistance and battery of accumulator of open circuit emf 110V and 0.5 Ohm resistance are in parallel what is common terminal potential difference?
please send me previose rrb junior engineer qustion papers
what is the effect of back reactive power on the generator ?
What is load boxes ?
WHAT TYPE OF DC MOTOR IS USING FOR ELECTRIC TRAIN ?HOW ITS FUNCTIONING ?
Define open loop control system.
How the capacitance og capacitor volatage transformer is decided?
current and voltage equations for a star connected load fed from a delta connected load.
What do you mean by pf of a generator? Power factor purely depends on the load (wether inductive, reactive or unity) then what does the pf mentioned on the generator nameplate means?
What is the diameter of electromagnetic field around a 11000/415v transformer ? Dose it affect people who live 3-4 meter beside it?
i need to calculate high voltage line power factor daily basics but there is meter reading kwh and kvah while calculating power factor kwh/kvah formula was right. for examble there is point c=13kwh c=1.8 lag c=1.2 lead and c=14.5kvah like that i know that p.f =kwh/kvah but c=1.8lag kvarh and c=1.2lead kvarh points i dont know if u know please reply
in battery charging room we find two fuses (one in positive other in negative cables ).why it is so?one fuse is ore than sufficient?
