State the principle of working of transformer, Electrical Engineering

Assignment Help:

a) State the principle of working of transformer.

b) A 230/110 V, single-phase transformer takes an input of 350 volt-amperes at no load while working at rated voltage. The core loss is 100 W. Find the iron-loss component of no-load current, the magnetising component of no-load current and the no-load power factor.
