Consider an ideal transformer on no load as shown in the figure. The supply voltage is V1 and as it is an no load the secondary current I2 = 0. The primary draws a current I1 which is just necessary to produce flux in the core. As it is magnetizing the core, it is called magnetizing current denoted … Continue reading Ideal Transformer on No load
The d.c, supply can not be used for the transformers. The transformer works on the principle of mutual induction, for which current in one coil must change uniformly. If d.c. supply is given, the current will not change due to constant supply and transformer will not work. Practically winding resistance is very small. … Continue reading Why d.c. can not be used on Transformer?
