Homework Help: Finding voltage and impedance

  1. Jul 21, 2013 #1
    Hi again. I just want to make sure I got the answers correct since this is a past year question (received from a senior), I don't have the answers.

    Power supply voltage E=10e^(jπ/4) [V]; Current I1=2e^(jπ/4) [A].
    The magnitude of current I2 is equals to current I1, but its phase is π/2 slower than I1.
    1) Find the voltage V.
    2)Find impedance Z.
