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.

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

A rheostat is a resistor whose resistance can be varied (changed).
