  • What is Transformers Voltage Regulation? Examples And

    No load current is flowing due to open circuit. When no load current flows, there is no voltage drop and reactive drops across resistor and inductors respectably. Voltage drops across primary terminals are negligible. In second scenario, the transformer is loaded i.e. there is a load connected to the secondary terminals of the transformer.
