Homework Help: Single-phase motor; Power factor

  1. May 15, 2006 #1
    a single phase motor draws a current of 12A at a power factor of 60%. calculate the in-phase and quadrature components of current Ip and Iq wih respect to the line voltage.


    i have problem understanding the question.
    is what i need to find is just the Ip (7.2A) and Iq (9.6A)

    that's all?

    Sounds right. But for those of us who don't work with power factor much, could you please define how the % power factor is defined? And then how you got the 7.2 and 9.6A numbers? Thanks.
