the PSAs?
i've done one for mechanics already, but i flopped it
my next one is on monday for electricity
have you done any?

I'm doing the electricity one- determining the resistance of a filament lamp- on monday as well.

How did you find the electricity practical? I did it today, but I have mixed feelings about how it went

Hi guys! I'm also taking this exam! I'm going through the quantum physics and I'm finding it hard to understand how to determine Planck constant. (Haven't really done the experiments in school and I'm going ahead of the class). So if anyone knows a source that clearly explains it let me know.
thanks!
thanks!

I've looked a the link at the top for the Planck experiment but I still don't see why the voltage threshold has anything to do with Planck constant.
Any help?

you're referring to the last bullet point of this pdf document, so the 4th page should help
i haven't done this topic yet myself, so my apologies if the pdf isn't helpful
