Question

Hi, im having a bit of trouble. Is the results on the far right the results i should be getting , because apparently there should be some negatives?

Thanks

Answer 1

Here the far end elements are resistor and capacitor only.we know for the RC circuit the power factor angle is positive only.Already you got only positive power factor angles. So these are correct.
