    Hello Everyone,

    There is some problem in complex number
    How V0=110.9<213.69?

    I think;

    I2 =-1/n I1
    I2=-(5.545<33.69)
    I2=5.545<-146.31
    ......

    V0=20"I2"
    =20*(5.545<-146.31)
    =110.9<-146.31
    true?
    thanks.

    Draw the phasor to get the correct answer.

    Does this help?

    Hi,

    Not sure if this matters anymore but, did anyone happen to notice that 213.69 degrees is the same as -146.31 degrees ?
