    Experiment to show that current leads voltage by 90° in capacitor (Using RC circuit & Oscilloscope)

    (1) I also used 1.2 k ohm, 1 micro farad capacitor and 4Vpp 100 Hz Sine Wave. The result is 89.28 ° So, you can use other resistor and capacitor. (2) My scope will jump from 148 micro second to 152 micro second (instead of 149 micro second) when I measured the phase difference using cursor of...
