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!

[@myhometuition]

Glad it was helpful!

[@olivialew8175]

Very helpful, this topic is a little troublesome but with ur explanation I can fully understand the concept. Thank youuuu

[@myhometuition]

Glad it was helpful!

[@miguelperez581]

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

[@teqniaskill8136]

Simple to the point and hit directly to the my biochem drive🔥

[@hashimjeddahksa8067]

I think it is reverse.....between bright and dark

[@hariprasadt1393]

yeah I think so too

[@olivialew8175]

What do u mean

[@hariprasadt1393]

Olivia lew check the video I think there’s some mistake

[@meilingsoh4458]

@@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

[@myhometuition]

Happy to help, keep watching :D

[@Vishal-lw6hn]

This really helped me with my homework, thank you very much

[@myhometuition]

Glad to hear that!

Thank you so much sir 🍀🍀

[@oneaboveall3374]

😭😭😭 I feel so good after understanding it... 😭😭

[@myhometuition]

glad to hear that 😭😭

[@johnnymehanna2340]

What if i need to be adjustable, where to put the variable resistence? Thank you

[@nithiyakalyaaniapmanickamb6534]

The video was really useful but I think it is upside down when it comes to dark and bright

[@auditor9927]

My freind there is mistake in ur circuit is that the ldr should be down and resistance on top. Else it works the reverse.

[@eveningdrawingchannel5241]

Best thinking in theoriotical

[@ramtinnazeryan]

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?

[@ibraheemhaque5752]

it starts from positive terminal

[@kevinclement6137]

@@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.

You're most welcome

[@itsmeracoon7907]

Jeez man where are you from I spent the entire video just trying to pin down where that accent is fro

[@tungsongkhai4880]

most likely from singapore or malaysia

[@millifire693]

No thanks, not understood
