Answer / bhadrappahr

Which is transferring the power from one circuit to another
circuit by stepping out or step down the voltage correspondingly stepping down or step up the current without changing the frequency is called transformer.

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.
