The final expression we get is i=I cos(wt) which we express as i=I sin (wt+90). We can very well express it as i=I sin (wt-90). gvfs is not correctly installed

"WebFeb 6, 2009 · The gate of a MOSFET is (almost) a purely capacitive load, since the gate-to source input resistance is hundreds of megohms. This also applies to the input terminals of most CMOS devices. Upon initial application of AC power, the input to a capacitor input filter of a conventional power supply presents a momentary capacitive load, since virtually all … " - Purely capacitive load
