Answer Posted / manikanta..{munna} geethanjali
load is something which dissipates energy..!! in case of
transformer , ideally a transformer is power source
device...and but this acts as load practically bcoz of
losses in it...!!!
coming 2 d rating any load is alwayz rated in kw..!! here
in a transformer the losses are due 2 copper and iron which
depend on current and voltage respectively...there fore v
rate the transformer in v*i !!!! and they is no use of
including powerfactor.
