Power factor means Cosine angle between Voltage and Current
so cosine rang is in between -1 to +1 so power factor unity
means one(1)
For only inductive load current lags voltage behind 90deg
For only capacitve load voltage lag current behind 90deg
For only Resistive load current and voltage both are same
phase

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.
