Answer Posted / pratheesh
Transformer is a power source(supplier) whicah can
deliver X amperes at rated voltage. So units of these
values are Voltag(V) and Current(I). It means all the
power delivering equipmets such as Transformers and
Generators are supplying I ampere at V voltage. Thats y
its rating is V*I == V*A
Power W= V*I cosQ.
Not V*I. (It is in DC)
