sir your reading are a bit incorrect in there graph part ... I think you have taken 1 small block as 0.03 but if we add them up by 30 blocks it makes 0.9 ... and if you take 0.033 as one small block it makes 0.99 for total 30 small blocks ... so won't examiner deducts marks for this ?? and in the last part you took the Y-intercept value wrong.
sir, if our value was like for example 0.1234 units (in table)and the way our scale (of graph)is it only allows a accuracy of 0.01 units would we round off our value to nearest 0.01 unit when we plot that particular point on the graph or can we plot in between the small square of the graph by estimating
Good question. Keep the scale of your graph according to your precision in table. However, while plotting its not a hard and fast rule to plot exactly to precision. You can round it to manageable value.
thanks for this video, i have 2 questions. firstly, isnt the scale on the y-axis considered awkward? and secondly, after drawing the best fit, the 2nd and 3rd points are both below the line. doesnt this show systematic error and make you lose a mark?
He mentioned that the points on any scale shouldn't be fractional, he used whole number values. Yea ik in between there will be fractional values but you can't eliminate them at all. For your second question, line of best fit doesn't mean that it passes through all points. Examiners knows that there are uncertainties in values because of s.f and other stuff. It doesn't denote systematic error

I think that the electricity practical is easy except setting up the apparatus
Yeah I agree with u
Thankyou sir. I understood well. The details of marking was really helpful✨
Most welcome 😊
It was really detailed and explained so well
I understood the plotting and table so well
Thank you
Sir that beat was not needed
Thank you! Very high quality video
IF MY PRACTICAL GOES GOOD AFTER WATCHING THIS VIDEO WALLAHI IM GONNA BE A FAN OF URS CHANNEL !
How it went ???
doesn’t sound like it went good
@@pixa1z lol
@@pixa1zDamn seems like it😅
thanks man, you really saved me here.
Dude you writing an exam too😂. Best wishes bro
Sir you didn't made the third loop

Hi i do not know if I'm wrong. However, in the sets of reading(4) 1.10/0.41= 2.68292 ... So would you not round it off to 2.68 not 2.69?
God bless your soul

If I write the length as 100mm for 10cm in the table is it right?
Sir i think you did not finish connecting the second voltmeter in parallel. Am i right?
Thank You Really helpful.

Good video sir 🙌🏾
the value of C at the end is wrong! In part d)iii) above, you got C = 0.85.
Thank you for pointing that out
🙂thank you very much sir
U took value of C( y intercept) wrong in last part
Won't the unit of B in (e) be ohm power -1? how is it just ohm
thanku
AoA sir can we start the plotting of graph with 5 and then 10 and so on
Thanks sir
What paper is ..month ..32..33..and year
SIR DO YOU HAVE A VIDEO ON HOW TO CONNECT IN Parralel vs series
Thanks I will work on it
Salaam sir, does the Learner's Academy have classes for alevels too?
Yes both A levels and Olevels. All subjects.
Walikum salam
You made a mistake at the end you have took C as 0.45 which is actually the value of A the value of C was 0.85
thank you! will correct it in future :)
how many significant figures do u take for y-intercept
least significant figures in your data or 1 more than that.
05:45
Sir why you didn't connect switch
I manually disconnected the wires. Same thing but you should use switch
@@CentaurusAcademy ok
Thank you
shei toh
3 hours before exam!
You can ask help in exam ? Really ????
Yes you can. But 2 marks for major help is deducted
