Find the Phase Angle Help

  1. Mar 11, 2010 #1
    Hi , there is a circuit with AC voltage with a resistor followed by a capacitor in series, and at frequency 1760 Hz I need to know phase angle, the peak to peak separations for the voltage source to the voltage across the capacitor is 15 ms...how do I find the phase angle?

    I already found it theoretically using arctan (wRC), but I'm not sure how to do it practically.

    Thanks.

    Compare the 15 ms to the time for a full oscillation period.

    If the 15 ms were one-half of a period, then the phase angle is 180°.
    If it's a quarter of a period, the phase s 90°.
    Etc.
