IC 741 is opampIC..moreover AND OR NOT ICs also have '74' in them.. why is that number specifically used?
At the starting of dc motor and syn.motor and induction motor high current flowing through the winding. Due to this the windings burnt out. To avoid this different types of starters are used. But incase of transformer what Will be used (At starting no emf is induced in the primary winding)?
pf of synchronius motor is unity, is it axact(=one) value. ?
what is the difference between neutral and earth
which is batter in construction job,ELCB or RCCB?
WHAT ARE THE EFFECTS OF SERIES RESONANCE AND PARALLEL RESONANCE ON THE CIRCUITS PARAMETERS?
