Can Dc Be Applied To Transformers ?

1.	Can Dc Be Applied To Transformers ?
Answer» No Transformer works on Faraday's law of Electromagnetic Induction for which current in COIL must change. If DC is applied current will not change and transformer will not WORK. PRACTICALLY WINDING RESISTANCE is very small. For DC ,inductive reactance is zero and frequency is zero. Therefore impedance is low. Thus winding draws more current which may damage the winding. No
