I have looked everywhere to have this explained to me - absolutely brilliant. Thank you ! I just couldn't understand how a LDR could turn a nightlight on, since in low light the resistance is high. Only doing GCSE Physicis (trilology), but there was a 6 mark question at the end and I was really struggling with. Thank you so so much.

Bulb resistance is very low only in ohms and LDR still high in Kilo ohms how 1 amps current will go through LDR circuit during day in light.

Thank you for the explanation. I had a power line crew running secondaries to streetlights. I asked them if they isolated the feed and they said it didn't matter because the photocell isolated the power from one streetlight to another. Your video explained to me how wrong they were and the potential for injury was real.

Perfectly explained, I was literally thinking about the logic of why is resistance increased at night when clearly current will be less, but now I understand so thanks for that. But just wondering is there an easier way than this to turn street lights on because this method is a sort of reverse psychology kind of method, isnt there a faster method where amount of amps is regulated to low/high staright away and doesn't need an ldr in a circuit?

How much I had to search to eventually understand how LDR is used to control lights. Such a simple explanation! Everywhere you look you find the same thing, resistance of LDR increases as the intensity of light decreases and vice versa but how does that explain the use of LDR in controlling lights? I just understood without even watching the whole video. Thanks

@doubletrouble4815

i finally understand why a lamp at night turns on when the resistance of the LDR is high- essentially the flow prefers flowing through the lamp as there is less resistance. Likewise, during the daytime when the LDR's resistor is low, the current mostly flows through the main part of the circuit, not the parallel bit. The lamp could have a slightly higher resistance than LDR
@doubletrouble4815

actually, more like less current will flow through the LDR at night when it has a high resistance, leaving more for the filament bulb.
