Need help regarding Automatic night lamp circuit

Hi ,

I made 

Automatic night lamp

circiut that is available on this site but I do not have 100k variable resistor plz suggest me any way how can I compensate the unavailability of 100k variable resistor in that circuit.

while testing that ckt in lab you can try with 20K/ 50K/ or any(variable resistance) higher one…

[Sanjeeda]

Actually even 20k is not available in the lab .plz suggest me some other way…

                          thanx

 

[dagakshay]

which is avialbale with you???

[Sanjeeda]

only 5K is available.

[dagakshay]

grt…. tell me the voltage value across the LDR in dark and in light condition…. i will tell the alternate resistance value

 

can you get that in market ( variable resistance)
