Learn how and why to determine the Thevenin equivalent circuit for any linear, bilateral AC circuit (i.e., one with independent sources, resistors, inductors and capacitors).

At 11:51, why do you take the voltage over the 16ohm capacitor as the voltage between a and b? Wouldn't it not be the same because of the 10 ohm capacitor? I understand the open circuit is caused by the current source being set to 0 but why does that 10 ohm capacitor not interfere with the voltage?

There will be no current through the 10ohm capacitor, so no voltage across it.

At 10:30 why is the current from the source taken as negative?
@ElectronXLab
@ElectronXLab 6 лет назад
Because when that constant current source drives current through the Thevenin equivalent resistance, the current i going from point b to point a, but we want to know the voltage from point a to point b.

8:40 u took capacitor as 10 ohms while calculating the th impedance shouldnt it be -j10 ohms?

You're right I messed that up, I meant for it to be a resistor. At 7:20, I called it a resistor but drew it as a capacitor. Sorry about that.

8:40 gave me (14.769 - 35.846j), or 29.768 angle of minus 60.255

then plus 10 becomes 24.769 -35.846j

You presumed the radian frequency of 1 radians per seconds which means your f= 1/2pi cycles per seconds from w=2pi.f
