Class of 2024 here! Never understood this chapter amd here i am preparing for my trial exams which is in less than 90 days! The future seems bright like these circuits

[@MlungisiNkosi]

It is humbling to hear that… All of God’s best

Teaching is your calling, you were born for it. You explain everything so eloquently and clearly. It's almost impossible not to understand these concepts the way you lay it out for us. AMAZING job, as usual. THANK YOU so much for doing these videos.

It's my pleasure...

I still come back to this message... I really cannot be grateful enough.

You truly are "Mlungisi" cause wow I'm in metric and it's my first time understanding this topic after so many years 🙊. Thank you so much.

Thank you very much sir.Your teaching has shown how physics is very easy❣️🦋. As for the Challenge the Voltage I calculated for the 20 resistor is 10V✍️

[@MlungisiNkosi]

Music to my ears... And that's the point I tried to prove. Physics isn't difficult. It's how it is taught that sometimes makes it seem challenging... A genius has been unleashed.

[@MlungisiNkosi]

You just know how to drive me to tears 😭

[@Movingintolife]

Sir you are so helpful! I listened to what you said is that it divides potential(V) and i made a ratio(4:8) knowing the V1 = 4/12=15V,and 8/12x15=10V for V2!! Im so happy we got the same answer and I'm writing tomorrow and I'm actually excited! yay!

i don't even know what to say for a whole term i've been trying to understanding what is electric circuit and i just want to say that you very much mr nkosi you really helped me from a girl who scores 11/50 in test to 90/100 in my exam thank you thank you thank you🥰❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤

[@sydwellrangile4495]

Sir this is how I worked it. V = I x R V= 0,5× 20 = 10 volts .

[@MlungisiNkosi]

You are a genius 😊

[@nokwakhemasinga2671]

I did the same too😁and got the same answer

[@AdvocateRathogwa]

I worked it this way I=V÷R 0.5=V÷20 Thus V=20 volts.

[@giant_spiders9681]

I do believe that at 14:50 you're confusing conventional current with the direction of the flow of electrons. Due to you implying that electrons flow from the positive terminal to the negative terminal. When in actuallity, it's flowing from negative to positive terminals.

[@MlungisiNkosi]

I definitely am using conventional current as per the requirements in the South African syllabus but you’re absolutely correct about the movement of electrons

If in a circuit you are given the current but not the total current and then the question requires to find the unknown resistor how do you tell that you have to use the given current or the total current Hope you understand

Pardon me sir, I will I be wrong if I say: the internal resistor is in series with the external resistance, since the internal resistor and external resistance share the emf which is the maximum potential difference, in addition the current passing through the internal resistor is the same as the current passing through the external resistance.
