Hello everyone, I have a very simple question but for some reason, I couldn't find the exact answer to it on the internet. Let's say we have a formula y = k/x where k is constant and x and y are variables. Assume that I am given the absolute uncertainty in x how should I calculate the...

Yes It did but I am still confused. I need to find the name of the working principle that lays in the basis of the photodiode, and I guess if I found the answer in google I wouldn't ask the question here.

Hello everyone. I feel myself a little bit confused because I can't understand the difference between the working principle of the photodiode and the photoresistor. The photoresistor changes its resistance under the influence of light while photodiode changes the current across iself. Is this...

This is amazing the circuit will be so basic now.! Yes I have already decided to use lux to measure illuminance. But thank you guys for all your assistance, you really helped me)

Thank you very much for your assistance, I was a little bit surprised to see such a broaden answer. It will take me some time to digest everything written above). As for my experiment, I had this light bulb moment when was thinking about research question for my extended essay(Every IB student...

It seems to me that, the apparent brightness is the most suitable quantity to use. https://www.e-education.psu.edu/astro801/content/l4_p4.html

Hi there, My name is Anar Kazimov and I want to carry out an experiment related to the sensitivity of the photosensors(photodiode,photoresistors and etc.). To find their sensitivity I am going to change the distance, from the light source to the sensors, and compare the change in output...
