What Is A Transformer? Principles, Types, Applications - Electricity …
网页A power transformer is a device that converts alternating current from one voltage level to another, either to "step up" or "step down" voltages. The working principle is based on Faraday's law of electromagnetic induction. When an alternating current is applied to the primary coil, a magnetic field is created around the core.
