thank you so much for this explanation! ive been pulling out my hair trying to understand the difference the positions of the LDR makes and this is such a clear, simple and quick explanation!
Glad it was helpful!
Very helpful, this topic is a little troublesome but with ur explanation I can fully understand the concept. Thank youuuu
Glad it was helpful!
when computing for the total current and resistance of a transistor controlled LDR circuit, do I use the Mohms of the LDR or just the hundred ohms of the LDR
Simple to the point and hit directly to the my biochem drive🔥
I think it is reverse.....between bright and dark
yeah I think so too
What do u mean
Olivia lew check the video I think there’s some mistake
@@hariprasadt1393 No, it's correct. To light the light bulb at night, you just need to switch the position of the LDR and resistor that form the voltage divider.
🤣🤣🤣🤣
SIR I RESPECTED YOU SO MUCH!!! MY TEACHER FAIL TO EXPLAIN THIS SIMPLE THINGS TO ME BUT YOU CAN!!
After 10 minutes,i quickly understand this concept! Finally i can sleep peacefully after 3 days of researching about this topic only to understand it deeply,i'm just curious hehe
Happy to help, keep watching :D
This really helped me with my homework, thank you very much
Glad to hear that!
Thank you so much sir 🍀🍀
😭😭😭 I feel so good after understanding it... 😭😭
glad to hear that 😭😭
What if i need to be adjustable, where to put the variable resistence? Thank you
The video was really useful but I think it is upside down when it comes to dark and bright
My freind there is mistake in ur circuit is that the ldr should be down and resistance on top. Else it works the reverse.
Best thinking in theoriotical
I had struggling understanding the behavior of the current. but I reversed the current in my mind and your explanation suddenly made sense. I hope I am not mistaking but I think in DC it is OK to assume current in either direction. Am I right?
it starts from positive terminal
@@ibraheemhaque5752 it depend what convention you are using, Conventional Current starts from + to - but if you are using Electron flow convention than it is the other way around. Generally everyone is using the conventional one.
Life saver
Very good explanation
thank you :)
very well explained
Thanks for liking
Nice explain 👏👏👏
Glad you liked it
Thank you sir!!!
Most welcome!
I LOVE U
Thank you so much
You're most welcome
Jeez man where are you from I spent the entire video just trying to pin down where that accent is fro
most likely from singapore or malaysia
No thanks, not understood
