25:29,I’m so sorry for all these questions I’m asking sir,but please,in my textbook I have that,efficiency (E)=R/R+r X 100/1, and I just solved for similar question with the formula you gave and they cancelled my answer.I wish I could snap it and send to you. Thank you very much sir
The questions I'm solving are Jamb exam questions which are Objectives... So solve as fast as you can. If they were theory, maybe diagrams could come in
@@jonahemmanuelofficial Also, from the first example, we were asked to calculate the current flowing through the external resistor. But in the solving, you calculated the current flowing the external resistor as emf/ total resistance in the circuit i.e R +r So, I got confused, shouldn't I=E/R instead of E/R+r ??
Exactly, Sir in the first example,we were asked to calculate the current flowing through the external resistance which is supposed to be,E=IR,but then instead of solving with R(12ohm)which it the external resistor,you solved with (21 ohm) which is the total resistance,I got confused.or maybe I don’t understand
I like ur teaching
Thank you
Waow, this is nice
Thank you.
i like your videos man with you every one wiil pass physics you simplify the work in my class
Awesome.
I'm glad you like them.
Thank you very much 😊
You are the best
Thank you so much 👍👍
Thank you boss I love the way u teach
But we will love diagram sir for better explanation
Ok
Thank you very much, Sir!
Always welcomed 🙂
Thank you master ❤
Always welcomed dear 🙏🏻💯👍
This was really nice
Awesome.
Glad you understood.
Thank you sir
Always welcomed 🙂👍
You're bless
🙏🏻👍👍
Thank you

Ok then
Thanks brother
Always welcomed 😊
Don't you recommend drawing diagrams when solving these types of problem?

Thank you sir sir please do you have any video on solubility in chemistry 😓,can't really process it
We'll make it available as soon as we can
You should be holding organic chemistry classes
I already am
@@jonahemmanuelofficial is it topic by topic bet me u will get more followers it will be helpful
Pls are the question JAMB questions
Yes, Yes, Jamb questions.
Am getting the answer in exponent form can I leave it
Punch a calculator and get the real value in decimals
Pls can we watch it because of WAEC
Yes Yes... Same thing
😮
👍👍👍👍
Pls sir I messaged this number is not on whatsapp sir
