When you repeat readings for voltage and current in the internal resistance practical and average them, how would you be able to set the variable resistor to the same resistance each time in order to be able to average voltage and current for a particular reading? Would I have to describe that in my method to get top marks? Thanks.
you actually vary the resistance. In practice it's just a variable switch and you just change it to a new position. This level of detailed is not needed to score the tops marks : )
Hi. Please could you make a video on how to get into level 3 in the 6 mark questions I think it would be very useful for many. Perhaps a formula for structuring practical answers and other 6 markers to ensure 5 or 6 marks out of 6 is gained could help. Many thanks.
Thanks a lot for the idea! Generally there is no formula as every question is different but I can come up with lots of useful advice. I have included some of it here: th-cam.com/video/F5iMGRwzUNM/w-d-xo.html Hope it's helpful!
Thanks sir for an great video for an aspiring civil engineer
anytime! good luck with civil engineering, you can do it!
