Transformers Specifications | Engineering360 transformers are used in electronic circuits and come in many different types and applications. Power transformers are sometimes considered to be those with ratings of 300 volt-amperes and below. These transformers normally provide power to the power supply of an electronic device, such as in power amplifiers in audio receivers.
