So for an ideal capacitor for t1 to t2, v initial is 10 volts.
00:18
The capacitor charges through the diode until vc is equal to 10 volts.
00:24
Assuming the capacitor is initially uncharged, the diode is a forward bias, so vc is greater than 5 volts, and clamps the output voltage v0 to vc minus 5, which is 5 volts.
00:39
Once vc reaches 10 volts, no further current flows, and vc remains constant.
00:44
From t2 to t3, vi is equal to minus 20 volts.
00:50
The diode becomes reversed biased, so vi is not smaller than vc, preventing the capacitor from discharging, so vc remains at 10 volts.
01:01
The diode is the upper voltage.
01:05
V -0 is v -c -minus 5, which is 5 volts.
01:09
And from t3 to t4 v i is 10 volts so the dires for biased so we see remains clamped at 10 volts so v0 is equal to vc minus 5 which is 5 volts and so for the ideal capacitor um the voltage is just constant over time as the capacitor does not discharge it's constant at 5 volts and for a non -ideal capacitor, let's call this for an ideal capacitor, for a non -ideal capacitor, the capacitor discharge through the low resistance, r is 100 kilo -ooms...
