A transformer's capacity is rated in volt amperes(V.A). This is the product of the secondary winding's current rating and voltage rating.

What happens when unequal voltage ratios of transformers used in parallel operation of transformers?
You cannot connect transformers of different voltage in parallel. This is because circulating currents will be set up between the two transformers that may exceed their rated currents.
Why distribution and power transformer are rated in mva?
Transmission transformers are rated in mva. Distribution transformers are rated in kva. Power transformers are measured in va. There are, of course, exceptions, but this is the normal nomenclature.Answer (for UK terminology)In the electricity supply industry, the name 'power transformer' is used to describe those transformers used in the transmission system (400/275/132-kV levels), while 'distribution transformers' are those used in the distribution system (33 & 11-kV and 400-230-V levels). Power transformers and primary-distribution transformers are rated in megavolt amperes (MV.A), while secondary-distribution transformers are rated in kilovolt amperes(kV.A).Note that 'mva', 'kva', and 'va' are incorrect symbols for 'megavolt ampere', 'kilovolt ampere', and 'volt ampere'. The correct symbols are shown in the above paragraph (except that the period, or full stop, should be placed above the line).However, I suspect your question is really asking why are transformers rated in (mega) volt amperes rather than in (mega) watts? The answer is simply that the load that a transformer can supply is determined by the product of the transformer's rated secondary voltage and rated secondary current -the product of which (for alternating current) is the volt ampere, not the watt.
What is DCR in transformers?
It is dc resistance, use to measure the rated current at primary and secondary side
What is transformers job?
It depends on the type of transformer:transmission/distribution transformers step up or step down system voltagesisolation transformers electrically isolate two systems without affecting their voltagesmatching transformers are used in electronic circuits for impedance matchinginstrument transformers step down voltages (voltage transformers) or currents (current transformers) for measurement or protection applications
What are at least 2 types of electrical transformers in science?
A variety of electrical transformers are produced for a variety of purposes. All of the types use the same principle discovered by Michael Faraday, and employ many of the same parts. The various types include. Audio transformers, Instrument transformers, Pulse transformers, Power transformers, RF transformers. .
