Good day sir. I'm a teacher by profession, specializing in maths and physical sciences. I'd like to personally thank you for making my teaching career a successful journey. Ever since I watched your video my teaching has transformed. This is an appreciation comment. Keep up the good work.
Wow... Thank you so much for the comment. I am more than blessed to play a small part in assisting you to become the great educator you were meant to be. Please send me an email so that we can keep in touch.
In 2010 i had the privilege of attending your classes at grace bible church, from that day physical sciences became my love. I'd take your lessons to my group that and everyone passed with great results. I would not have been where I am today without people like you. I have made a promise to extend the blessing by tutoring everywhere I go. Thank you.
I can't believe that I was hating on such a nice subject , you have proven that physics is not hard . I can't thank you enough for making my journey this year easier ! You remain the best 🙏
I was writing a physics exams yesterday I don't think I did amazing but it was good enough. I go to an online school so when you have a bad teacher, that's basically it. Your videos are heaven sent thank you for them. I am going to study for my chemistry paper now, hopefully I will do better...fingers crossed.
Well, I'm grateful for your honesty about where you are in terms of your results right now... The great news is that you won't remain there. Judging from your statements, you're doing something about it... I promise you, I'll give my absolute best to teaching you in the best way possible. I know the result will be phenomenal. Let's keep up the hard work until we see that change.
I've seen teachers but sir you are one of a kind . Thank you for rescuing me in this hell hole i was in ... in the hands of my teacher but with you im ready for my preliminary exams ✊🍾
Not me who is watching all of his videos now 2 topics left umm they are very helpful; May the Lord keep you safe for us uncle u are really a life saver matric 2024 let's gather here finally understand circuits
🤗🤗Wow I don't even know where to start. I wanna say a big thank you on your videos sir, they have really helped me a lot by understand my maths and physics. Last year I was doing grade 12 and honesty as much as I was trying to study and understand my class teacher, I even attended extra classes but I never understand anything. I had already given up that i wanted to change my subject this year but they told me that i couldn't change it now, because it already to late to change now i'll have to change next year. 😏😂short story is 2 weeks ago i was just sitting in my room crying to myself thinking that I'm obviously going to fail both of this subject coz i just study but never understand anything. I went on TH-cam saw your video I didn't wanna watch the first time coz i felt that the videos were to long to watch 😂few day later I was okey fine let me watch one video and honesty I'm really thankful for your videos now I can answer most of the difficult questions coz i know understand better. You are really the best teacher ever in explaining even through the phone wow I just can't believe thi. I'm really greatfully to God that i found your channel. It made me love maths and physics . Now I have so much hope that I'll do well then before all thanks to you sir and I believe that coming November I'll master my paper with flying colours 🙏🙏🙏🙏🙏🙏🙏🙏🙏I wish the best for you sir.
Sir I just wanted to get clarity on something. On the second last question, we were supposed to find the value of current passing on A2. Shouldn't it be the sum of the currents passing Through resistor B and resistor C ?
Sir on the second activity for A2 i got 3.5 A. I firstly calculated the effective resistance of the 4 ohm and 3 ohm resistor which was 1.71 ohms. I then substituted that into the Formula and got 3.5 A. I did that because they asked for the current passing through A2 and not the current passing through the 4 ohm resistor
I’m honestly mad for watching this the day before the exam. These videos are so in depth and so enriching but because I’m in such a rush I can’t truly appreciate the length of these videos😟
Thank u so much sir Nkosi I'm learning alot❤ and ur videos are super helpful to me I'm upgrading my matric and u are making my life so easy with ur videos 😭😭 I'm super grateful I've found this channel ❤❤🙏🙏
sir could you please mention mistakes in the bio when you find out about them as some people may spend like ten minutes trying to make sense of it but other than that you're a star! thank you for making this so simple.
Mr Nkosi your lesson is loud and clear, but can you please help me, what if they ask me to calculate the total resistance and assume we are also given an internal resistance, we must àdd the Rext with r ?
Sir I dont understand by making the 18 ohm and 9 ohm resistor one thing do we continue treating the circuit as parallel ... I'm asking cause you said the voltage for the 6 ohms will be 24v ... I didnt understand what you meant when you said because it's the only one
Hy I'm really interested in yours lessons sir I'm now a teacher of physical sciences in school........can we please have the video of electrodynamics lessons
Sir why not add the resistors for both the series and parallel and you will get ( 8 ) when you want to calculate for Voltage because you said in your previous videos Voltage is the Same everywhere in parallel !! And this is not a series circuit but a parallel one . I’m just confused
@@MlungisiNkosi so far so good, I'm understanding everything and I'd like to say thank you so much Mr Nkosi, I was stressin with the section of electric Circuit, reason is my physics teacher, teach us physics as if he is readin a novel and makin it hard for us to understand. I'd appreciate if you also do a section of Power and Energy as well🥺🥺tjoo, but so far I am understandin and I am attempting past papers.
Sir on the first question to find A I kind of calculated the I1 & I2 using the ohm's law formula then added them together and found the answer to be 4A😅 I actually solved the whole question with how I did it
A rheostat is a resistor whose resistance can be varied (changed). Often times, it's used to investigate the relationship between the current and resistance (Ohm' law) or to investigate the effect of the Internal resistance in a battery. I don't think you need to worry too much about it for tomorrow.

Sir I just wanted to get clarity on something. On the second last question, we were supposed to find the value of current passing on A2. Shouldn't it be the sum of the currents passing Through resistor B and resistor C ?
You're correct... It was my mistake. Apologies.
I had the same question 😂
@@MlungisiNkosi So sir, to clarify... the value of A2 should be 3,5A?
@@perle.malaba got the same answer. 3.51
@@siphetfomagagula5414 Thanks for that confirmation. :) Much appreciated.
I really appreciate your work sir you’re a total life saver 😞.
It is my pleasure…

I then substituted that into the Formula and got 3.5 A. I did that because they asked for the current passing through A2 and not the current passing through the 4 ohm resistor
Well done… 😃
i got the same
High quality lessons. Thank you
You're welcome
hello sir but A2s value is 3,5A not 0,5 because A2s value is made up of the sum of Ic and Ib
Thank you for that. Yes
Didn't you say at A2 we add the current Ic and Ib ...aren't we suppose to use both 4 and 3 ohms resistors?
Please let me know which question you are referring to by pointing to time in the lesson so that I can answer your question. 🙏🏾
@Utimna Mxi thank you so much for pointing it out. You're a star... It was my mistake. I apologise sincerely for that 😊
@@MlungisiNkosi thank you...
@@MlungisiNkosi so the answer should be 3.5 A right sir?
@@mphomurashiwa8154 absolutely right
Thank you Mlu you are the best man,I was so confused about circuits but it is supercalifragilastic acastastic
🤣🤣🤣🤣🤣🤣🤣🤣 Super what?
I'm glad I could help. Let's keep pushing...
Thank you so much for the video Sir. I understand this section better now
It’s such a pleasure ❤️
I’m honestly mad for watching this the day before the exam. These videos are so in depth and so enriching but because I’m in such a rush I can’t truly appreciate the length of these videos😟
😭😭😭
Maybe come back after exams and binge on each playlist yabo
@@MlungisiNkosi definitely!!
34:01 But sir what if i used I=V/R then straight away i put 6 where there's V and 12 where there's R and then i got 0.5A straight away
Is it wrong?
Thanks.. mlu.. u shud consider starting online physical science school so we can pay school fees 🤭 ur the best 🤝🙏
Just now I'll ask for 5tau... Don't tempt me 😂. I'm glad it's of benefit to you
@@MlungisiNkosi for the whole year 😂
thank god for you sir, heaven sent.
It is my pleasure... Thank you
For the second question.. What was the final answer for A2?
It should be 3.5A
You the best mr.. ♥️♥️
You’re welcome
You are good sir I am nailing this chapter😍

I'm super grateful I've found this channel ❤❤🙏🙏
I really appreciate your work sir
Thank you 😊
is the current Ib the same as A2?
No I made an error... I'm glad you picked it up though
Learning much from u sir
sir could you please mention mistakes in the bio when you find out about them as some people may spend like ten minutes trying to make sense of it but other than that you're a star! thank you for making this so simple.
Makes sense... Thank you for the suggestion.
physics is fun😂😂,thank u sir👊
Re a leboga you explain nicely God bless you
You're welcome 🤗
Sir don't you think the current on A2 is the current on 3ohm + 4ohm resistor?
It is
hi sir how do you differenciate and or tell which ameter belongs to which resistor
By checking which current passes through that ammeter
Sir can I ask: questions 2, parallel 2
Why did u choose to use total resistance series rather than total
Remember the principle is voltage with its corresponding resistance.
Mr Nkosi your lesson is loud and clear, but can you please help me, what if they ask me to calculate the total resistance and assume we are also given an internal resistance, we must àdd the Rext with r ?
Yes
🤝🔥Thank you sir !
It's my pleasure...
Sir I dont understand by making the 18 ohm and 9 ohm resistor one thing do we continue treating the circuit as parallel ... I'm asking cause you said the voltage for the 6 ohms will be 24v ... I didnt understand what you meant when you said because it's the only one
Yes the voltage remains the same even when you make it into one resistor
Hy I'm really interested in yours lessons sir I'm now a teacher of physical sciences in school........can we please have the video of electrodynamics lessons
Oh my word!!! Another fellow soldier... Keep up the good work.
I will cover electrodynamics in the very near future. Please send me an email.
Why are voltmeters connected in parallel to the resistors?
A voltmeter has infinite resistance. It will not allow current to pass through it…
Thank you Mlu...
Good day sir the second circuit A2 was miss calculated because you said that ammeter accounts for the two resistors 4 ohms and 3 ohms
It was a mistake… apologies
@@MlungisiNkosi I'm confident because of you :)
Sir may you please make a video of photoelectric effect
Of course... That's coming next week 😊.
@@MlungisiNkosi
Thank u so much ypur videos are very helpful..i see a distinction already😊💫
@@meganheher7975 definitely within your reach... Let's goooooo 😊
Put the video at 34min25 seconds. The current at I[B] is not the same as the current at A2?
I agree…
So sir is it major series??
I’m not sure I understand your question… Please rephrase.
Sir why not add the resistors for both the series and parallel and you will get ( 8 ) when you want to calculate for Voltage because you said in your previous videos Voltage is the Same everywhere in parallel !! And this is not a series circuit but a parallel one . I’m just confused
Sir, does this cover grade 11 content(circuit in parallel)as well?🥺
Yes... My approach was to begin with grade 11 content and build it up to a point where I introduce grade 12 content. I hope its helpful
@@MlungisiNkosi so far so good, I'm understanding everything and I'd like to say thank you so much Mr Nkosi, I was stressin with the section of electric Circuit, reason is my physics teacher, teach us physics as if he is readin a novel and makin it hard for us to understand.

Yessir!
Sir. Wait isn't 1/18 + 1/9= 1/3 not 6?
It is 1/6 and when you invert it, we get 6 ohms
Or sir. I saw where my mistake is. Thank you.
Can you help with rheostat I'm writing my final tomorrow
A rheostat is a resistor whose resistance can be varied (changed).
