I just found this channel, and i have to say that i'm blown away. Keep up the amazing videos, and i hope you know that you help a ton of people. Love from Denmark :D
I can't understand the initial situation of switch. İn this example is not the switch open at t=0? and the arrow shows up but it was already open I think I am confused very badly
@@MichelvanBiezen I didnt get it sir. Dont you think that the 30-V source has an effect on the circuit since before t=0 both sources are affecting the whole circuit. Can you enlighten us more?
would not the capacitor voltage at t=0 be equal to the voltage drop across the 20 ohm resistor due to the 30V source? and Vc at t=infinity be equal to the voltage drop at 20 ohm resistor - 10V ? please elaborate. thx
sir please @t = 0 isn't the switch open ? because as I have been following all your videos in this chapter I have agreed with my self that in a diagram when I see @ t = 0 its referring to the conditions of how the diagram looks at that instant in time or is that the wrong way to look at it ?

Best teacher by far, you don't get payed enough for the work you do. Thank you🙏
Thank you for your comment. (That is part of the pay and we appreciate it). 🙂

Abi ben de anlamam
That symbol means that the switch will open at time = 0 seconds and was closed prior to that time.

why when the switch closed no volt coming from the 30 v source ?
The sources are not affected by the closing of the switch. They continue to provide a potential difference between the terminals.

@@jrgelpe7196 The left Vs doesn't turn on until t=0 and switch opens
@@zwischenzug5324 can you tell why ?
WE WANT SIGNALS AND SYSTEMS FOR ELECTRICAL ENGİNEERİNG
Awesome video
WE WANT SIGNALS AND SYSTEMS FOR ELECTRICAL ENGİNEERİNG please sir. reaaly your lectures are amazingly understandable,
We are currently completing some uncompleted playlists. That topic is definitely on the list to be made in the future.

please elaborate. thx
Note that the 30V source is multiplied by the u(t) function which is equal to 0 before t = 0 and is equal to 1 after t = 0.

The arrow in the diagrams shows the direction of the switch which in this case opens at t = 0
