Question

Why a transformer cannot step up dc voltage?

Open in App
Solution

When a d.c voltage source is applied across the primary of the transformer,the current in the primary coil remains constant. Hence there is no change in the magnetic flux linked with the secondary. Therefore the voltage across the secondary coil is zero.Thus a transformer can't step up dc voltage.
