Understanding Photo-Resistors or Light Dependent Resistors, LDRs

[@SalaScience]

Nicely put. Your videos are well made and very informative. Very good tutorials, especially for beginners in electronics. LDRs are really useful, though the only downside is their response time as you mentioned.

Thank you very much! I'm glad the video was useful and I really appreciate your comment.

Very good. The dark resistance can be as high as 20Mohms for some LDRs and commonly is above 1Mohm for most LDRs I've used. Amazingly useful little devices!

[@ElectronicsNotes]

Yes it is possible to get some LDRs with very high dark resistance levels, but I wanted to give figures for more average devices. Thanks for the comment.

Nice video, well explained for beginners like me

I’m glad the video was useful.

There were some interesting uses of LDRs in early watt meters where they were used to effect the gain of an amplifier to produce a variable gain or multiply function. I was going to make a video on analog multiplier but think you would make a great video on this subject

[@ElectronicsNotes]

That is really interesting. I am not sure I ahve the experience to put together a video on the top, so it could be a great opportunity for you. Thanks for thinking of me though.

Very good!👍👍👍

Really glad you found the video useful. Thanks for your comment.

also describe axle benz formula

That would be good to incorporate into a video about LDR circuit design. Thanks for the idea.
