How do dc transformers work
WebMar 24, 2024 · Also, transformers work on AC, not DC, so the actual voltages are constantly changing with respect to each other in time. 0V is a relative term in AC. In fact, at 60Hz, A and G alternate being 0V 60 times a second. But it's convenient to think of the voltages as a magnitude, like when we put a DMM on said transformer and measure it. ... WebSep 12, 2024 · Transformers contain a pair of windings, and they function by applying Faraday’s law of induction. AC passes through the primary winding, which creates a varying magnetic flux. The magnetic field that results …
