now a shunt motor is practically a constant speed motor , then how does it meet the increase or decrease in the load ?

what will happen to the core losses if we perform the open ckt test on high voltage side of a transformer ?

What will happen if the interpoles in case of a generator have opposite polarities to that behind it in the direction of rotation ?

if the armature current in a dc generator is ac ( sinusoidal ) why doesnt the sjhape af armature mmf a sinusoidal (ni) ? armature mmf in case of a dc machine is triangular.

does the power factor of an induction motor improve upon used in parallel with a synchronous condenser , used commonly to provide a leading kva ?

can a synchronous motor be made to rotate in a clockwise direction ?

What will happen if the rotor of an induction motor is fed from a 3 phase supply and the stator short circuited ?

does magnetic interlocking take place in an induction motor ?

Why is the uniform distribution of the capacitor discs in a suspension type insulators essential , what can u do to improve the string efficiency ?

wht do u mean by constant flux linkage theorem ?

Why does the phase voltage of two healthy phases become equal to the line voltage in case of an ungrounded neutral 3 phase star connected sytem when a single line to ground fault occurs ?

why it is necessary to maintain frequency constant in a power grid ?

NTPC,

In a synchronous machine if the field axis is ahead of the armature field axis then the machine is ?

hi there i am highly enthusiastic about discussing electrical concepts , and hence i wud lyk to invit al do intrested to join me at gtalk and hav a dscussun of the concepts , ad me as a freind . my email id is rakesh.2k99@gmail.com

What is corona ? Mention its positve effects .
