This is a very good experiment (actually not an experiment but a lab activity). In 1998 I developed this lab activity so that all of the Physics students at Midwood HS in Brooklyn could use different colored LEDs and a variable voltage supply to measure Planck's constant. The students got very good results. Hardest part was that I had to hand build a variable DC battery variable voltage supply for each lab station.

Hello, What is the electronic circuit that will light the LEDs (red, orange, green, blue) one after the other by acting on the electrical voltage? And also without them lighting up almost at the same time. For example the green LED lights up almost at the same time as the blue LED. Thank you for your response.

Is Vo knee voltage? ...then u take from graph.... voltage at which current just flows is knee voltage...can we not take from data ?

Not all curves make same kind of sharp curvature so its better for accuracy that you take a projection ok Voltage axis and then ise them

Hello. I want to know why you set the resistance to 220 ohms in the video.

@AllLabExperiments 9 ай бұрын

5V is too much for LED. To save LED from getting damaged we add an extra resistance.
