Why transformer power factor taken unity?
It isn't! A transformer operating at no load has a very low power factor.
What is meant by the term ideal transformer?
ideal transformer is that which has no power losses.if any transformer transfer power to secondary without power loss then that call a ideal transformer

How a rectifier transformer deffer from a power transformer?
rectifier transformer converts acinto dc.but,power transformer convert step up or step down ac energy without changing frequency
What is Auto transformer and ordinary transformer?
auto transformer is a one winding transformer which is are used for step up and step down voltage without chang its power and friquncy
What is meant by rated voltage rated current and rated power of a transformer?
The ratings state the limits on voltage and current for operating the transformer at full load. The rated voltage times the rated current gives the rated VA of the transformer. Transormers are not usually rated directly for power because this depends on the power factor of the load applied.
Can transformer be operated on lead power factor?
Yes, there is no problem in transmitting capacitive VARs if they occur.
Is transformer is essential for rectifier?
no transformer is not necessary for rectification today most of power supplies have been made without using transformer in order to reduce weight and size of power supply.for example SMPS(switch mode poqwer supply)
What is a transformer and what principle is used in transformer?
A transformer is a static device which converts electrical energy from one circuit to another circuit without changing frequency, power, power factor. It works on the principle of faradays laws of electro magnetic induction.
Could you operate power plant without power distribution?
Yes, but without distribution there will not be any use of operating a power plant.
Is transformer an amplifier?
No. In an amplifier, Power Out > Power in. In a transformer Power Out ~= Power In (minus internal losses). An AC generator is more like an amplifier than a transformer.
What is the difference between power transformer and instrument transformer?
A power transformer is used to provide power (to your home, for example), an instrument transformer is used to measure voltage or current (for metering, for example).
