Are 110v transformers AC or DC?

in Electrical Engineering

Are 110v transformers AC or DC?

1 Answer

A 110V transformer is typically designed for **AC (Alternating Current)**. Transformers only work with AC because they rely on a changing magnetic field to transfer energy between the primary and secondary coils. This changing magnetic field is created by the alternating current, which continuously reverses direction.

DC (Direct Current), on the other hand, does not change direction, so a transformer cannot transfer energy with DC effectively. If you try to use a DC supply with a transformer, it won't work as intended.
