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 ✊🍾
🤗🤗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 RU-vid 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.
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 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
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 ?
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😟
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 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.
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 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
@@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.
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.
