Power factor rating of a machine....

I want to ask what does the p.f. rating of a machine provide information abt for eg. if it says 0.8 pf lag..thn does it mean tht machine can supply or operate only at 0.8 pf(lag)..currents?

    0.8 Powerfactor means 80% of your supplied power is used to do 'useful work'.

    Not really it just implies the load put by the device is capacitve due to negative power factor

    Indctive if positive power factor

    And Resistive if power factor is unity
