Mistake 1.11 The materials conductivity is increased when light is absorbed by LDR

[@kannuawasthi7569]

The main point

[@TheKakkarvfx]

light is absorbed by ldr

[@robertjones3613]

Again, we see with an excellent, clear and simple presentation, 9 individuals giving a "thumbs down"???

[@dhritishmanhazarika3894]

Thanks. Got a presentation on 28th!

It's this ldr can be used to open a pump on a day light?

Very nice explained .. Thank you .. I have one question that LDR is active device or passive device?

[@shatakshisingh2513]

Active

[@deveshwaribhatt]

@@shatakshisingh2513 thank you

[@exist_pubgmobile7183]

ldr or photocell is a passive device bro listen carefully

[@chaitrak1605]

Thank you madam
Do adaptive brightness settings in mobiles use LDR?

[@sairamnomula8710]

It's better to explain with the help of photos nd diagrams...

[@yashbharthimukeshbharthi8536]

If I connect LDR with a bulb and allow light to fall on it then what will happen? Bulb will light up or not? Plz ans this

[@electrical4you]

[@KavitaSharma-wo1lf]

Hi Electrical4U the material conductivity must increase right when light falls on ldr?

[@BaldurKhr]

At 1:09 says that "the conductivity is reduced when light is absorbed by the material" meaning the resistance increases if light increases.
Then at 2:05 the graph shows that resistance goes down as light goes up.
It's just a mistake, the latter one being the true one. The graph is good.

Nice Class
Thank You

[@vamsi5052]

As you said light dependent devices whose resistance is decreased when light falls on them and that is increased in the dark. then when the resistance is high in dark ,then how the current will flow through the LDR.

[@halimasumayya9890]

Then the current doesn't flow

[@Achu-pf9tq]

LDR is a sensor it is not a linear device

Please make a video on the construction of a LDR?

Hello Sir, I wanted to ask a question to you that there is such a sensor that when the light comes on and the lights turn off, tell me which sensor

[@charlieluo2910]

light sensor, we are manufacture for that , my skype : charlie 32978

[@tumzarelaxing]

great

[@hpppppgh]

why the resistance decreases when light is fall on LDR? explain properly

[@anandmohan4959]

Because it is made up of semiconductor and it has negative temperature coefficient that's why resistance decreases when temperature increases...
