Great video. The concepts nicely and clearly explained and not rushed. Thank you.
6:06 for Current Source.
Thank you for a very good lecture on Voltage and Current sources!
Excellent explanation. Thanks a lot for posting this.
9:25 sometimes you want a constant voltage "v" or current "i", supplied by a constant source is independent of anything else in circuit; but in some applications (amplifiers, or components used in amplifiers, like transistors), you want a v or i source that depends on some other v or i somewhere else in the circuit: "dependent source"
10:15 four types of dependent sources; the diamond-shaped component is the controlled source
@DragonsKing91 The source output is shown by the symbols on the source (on the diamond). + and - means that the output is voltage. An arrow means that the output is current.
put speed at 1.25 it's usefull
Salah GHANEM got em
excatly
More like 2x speed
Thanks
Thank you for your helpful lecture sir.
Very clear, thank you.
thanks a lot .. that was very helpful
very good electronic video lecture
Thank you sir.
Really useful info
@DarrylMorrell Awesome thanks for clearing that up for me.
thank you sir
thanks from india!
Thanks for the great lectures !!I appreciated your efforts for making these awesome videos.
I've a simple confusion on ideal sources,how circuit behaving if ideal voltage and current sources are connected in parallel?
does it behave like voltage source or current source or none.
Please help me on this.
Have a good day
InstaBlaster...
appreciate that
@FurySwipes2hit If the current is positive, then the arrow on the current source does mean the direction the current is flowing. If the current is negative, then it flows in the direction opposite to the arrow.
are you making videos for electronics engineering?
I subscribed
arrow is the reference direction, which means whatever current flow in that reference direction shall have positive value
Hi, so the arrow on the current source does not mean the direction the current is flowing? Thanks
information is good, play it a 2x for normal speech speed, at least for my country , wow this is from 2012
I've always thought the battery symbol looked stupid and was inelegant. You have to memorize which way the polarity is. The circular symbol is better because it shows the polarity.
use full
My lecturer was telling me today that an ideal independent current source has an infinite impedence, is this true?
Yes
تحسه يشرح وهو مهموم
Sir, do you have any email or facebook where i can ask for your help? I'm struggling with my Electrical subject. Hope you'll notice my comment. Thank you
How come voltage drops when current is increased ? isn't Ohm's law V=IR ?
Heating of resistance causes building of internal resistance inside the voltage source which leads to a voltage drop..
were you sleeping. just kiding nice explanation
Hey guys if you could test this out and give feedback it would be great! Search "Circuit Breaker vLite" in the Google Play Store!
I didn't know there were four types of dependent sources.
Lol, when I first heard this man, I thought he was George Lucas! :o
no wonder that your vids are pretty useful but the way you explain,talk or illustrate is soooo boring (no offense tho)
brother please work on speaking a little bit faster
no personal offence
The lecture was helpful. Though you need to prepare a lot on the topic you are giving a lecture about. You were lacking confidence and the way you teach is very dull. No offense.
Boring.
