Answer / moloy dey
1. In case of supply transformer DELTA/STAR is used to
ensure 440[Ph to Ph] and 220 [Ph to N] both type of consumers.
2. (A) Primary winding stays close to the core.
3. The power factor of a purely inductive / capacitive load
is always (A) Zero, Hence, the power drawn by a
pure/loss-less inductor/capacitor is VxIx'0' = '0' [Zero]
