Answer / bijoy kumar soni

impedence of a transformer is defined by the vectorials sum
of resistance, capacitance and inductance of the core of
primary winding

Answer / gtr

resistance offered to the flow of current in the
transformer ckt which gives rise to thermal heating. for
efficent functioning, impedance is kept as low as
possible .

As we use capacitor bank in 3ph ckt to improve PF, can we use capacitor in single ph domestric use, in house we have Fan,Mixer,electric cooker,iron,tube choke they also lag the system,because it is inductive load. if it is possible to improve PF of single ph system-- if yes- type of capacitor to be used,connection diagram, working in detail. if no-- list it.
