why we used.c source in the field of the alternator , why
not a.c source.

Answer Posted / javad

suppose the field is rotating and the armature is
stationary,we r applying dc to field. consider a single
conductor of armature. according to that conductor,while
rotor rotate say north pole is coming and have maximum
intensity then to low afterthat south pole is coming maximum
valu then minimu again norht. ie with respect to that
conductor it feel a sinusoidal flux.
if we are applied ac then we will not get sinusoidal
flux,hence cant produce sinusoidal emf.that is y.

hope my answer is correct

Is there a possibility to use such a treshold voltage for the NMOS part of a CMOS circuit that during the switching it will start conducting only after the PMOS part will be already closed, by this eliminating the leakedge current? Please note, I'm not asking about the well bias in standby mode, but about the "antileakedge" measures during normal operation.
