Question

What will happen if the primary of a transformer is connected to a DC supply?
a) Transformer will operate with low efficiency
b) Output voltage reduces
c) Output current reduces
d) Transformer may start to smoke and burn​

Answer 1

Hence, the transformer will not work. When transformer is connected to dc supply, steady state current start flowing through the winding. in case of dc supply self inductance is zero hence large current flows through the primary winding which results transformer get damaged
