Hi sir, I looked at the OCR specification and saw there was another learning practical part which said "techniques and procedures to investigate the charge and the discharge of a capacitor using both meters and data-loggers" but it was also labelled under PAG 9 so I wondering if its that different from this one
lots of different variations of experiments, this is the discharge bit. Typically in the lab you may be asked to produce a graph of charging and discharging.
If a capacitor gets only discharged when the circuit switch is open why is it that in this experiment Switch 2 is closed when it's discharged, should it not be open?
Excellent question. Not enough, in A Level Physics think of the standard experiments as "guides", you need to know them, but as in understand the principles of why something is happening, rather than memorize them. Typically ideas from them would arise in a new situation.
@@zhelyo_physics ah ok ok sir, please could you attach a link of your playlist that covers the practical aspect such as uncertainties graohs, practicals, thank you
I tend to include a lot of the practicals in the videos but here is a list for this: th-cam.com/video/qFgVrOVWdVY/w-d-xo.html , also this video for uncertainty: th-cam.com/video/WOckc29sZJA/w-d-xo.html let me know if something doesn't make sense! Good luck revising!

hi sir i was just wondering whether all of the videos in this experiments folder are all the experiments we have to learn or are there any more?

Hi, when discharging the circuit, is switch 1 kept closed?
We leave it open : ) Hope this helps!
@@zhelyo_physics why is the switch kept open? wont the capacitor start charging again, and the emf be alos shared with the resistor?
sir isn't it plot lnV against time, I think you accidentally said ln(v/v0) as lnv0 is our y-intercept?
yep it is! Ln against time it is : ) typically it's written as ln(v/V) but the"/V" bit just means the unit
