Believe me this channel is the only way to get successful in your lessons guys. I love and respect this guy who runs this channel. Just lovely, easy and undrstandable.❤❤❤❤❤ Hope this channel become the number one on TH-cam.
you've literally saved me. i am literally studying all the maths and physics topics from this channel since i don't understand a thing my teachers teach. I love these!

You’ve helped me so much honestly. I used to be in set 5s but after watching your videos I understood science so well. I’m in set 1s now and I’m grateful for these videos. Thank you so much for creating easy to understand videos.
Thank you, I’ve got grade 7s and 8s now in science (just got my end of year results back) and its a huge accomplishment from my previous grade 2s and 3s :D I just gotta work even harder for next year since my GCSEs are next year.
These videos are really beneficial. In fact, they are more imaginary well-explained, and engaging rather than listening to a boring lecture in a huge hall where students are packed all the time
The videos are great and helpful. Just watch few videos on your topic and you're good to go for the exams!! Keep up!! I love the contents of this channel.
thankyouuuu sooooo muchhhhhh all this resistance adds up, current and voltage stuff was so tricky I swear I couldn`t understand it after like 4 times of revising this topic. THE VIDEO HELPED SO MUCHHHHH!!!!!!!!!!!!!!!!!!
Hi, I like the way you explain and draw, in my text book, I can't really understand, but here, I can totally understand well!!!! and you've answered so many questions that I've think about, even my teacher cannot explain so well! And as you explain so minimalist, but you have list out all the main point! It is very helpful for me, I've cry when I learn physics and it's so hard, but when I watched this video it really helped me so much. And the math, chemistry, biology video in this channel also helped me a lot a lot. And I got very good mark for my science and math. thank you so much!
Is there a way to calculate the resistance of an individual component? I understand you can find the total resistance, voltage, and current of the circuit with V=I x R but what about specific components, also is finding the resistance of a component relevant for igcse edexcel physics, Could I be asked to find the resistance of an individual component in an exam? hopefully, I haven't bombarded you with questions, and thanks for the easy-to-understand videos, your channel is one of the few that provide science lessons I can understand without confusion.
In series and parallel circuits, how can I find whether there will be an increase or decrease in current or potential difference caused by a resistor? . Do the the same/shared current and pd rules still apply? Thanks
Question, which way would be considered backwords or front for the battery , im sorry im not sure and idk if its because i missed someone or if you forgot to say.
You forgot something important. Which one of the bulbs is brighter? Which one uses up more energy? It's confusing because the one with the greater voltage also has more resistance. So you would think, if it resists more, it shouldn't get as bright. Like, there is a very high voltage inside an electric socket, but the plastic cover resists that, so when you touch the socket, you don't get a shock So does the higher resistance bulb really get brighter? If so, why?

I have a science exam tomorrow and this video surely proved helpful in understand circuits.😊
You're great seriously.... I've learned many things from you
This should be what teachers how teachers are teaching
This guy right here is a life saver..
You're not alone sis
Are you Humaira Shaikh from Belvedere Spring School?
These help so much and my teacher loves all of your videos!
Aw thanks Taylor, we're so glad 😇
thank you to much I came after 2 weeks from the school but now with your help am in the class understandig everything
The explanation is phenomenal !!
Thanks I will pass my physics paper
Could you do a video on the difference between Potential Difference and Electromotive Force?
physics exams in 5 mins aaaaaa thank u
during the video I decided that to subscribe and add this channel in My library ! Thanks Sir
Really glad it’s helping :)
@@Cognitoedu even I subbed before
my google classroom crashed and this is my saviour.
Haha 😆🤣
Ty this video is really good and easy to understand!!! Please continue to make videos like these tyyy👍
Heroes come in many shapes and sizes, I think you can be considered one.
🥰 Thanks FruityTruity
I wish i knew about this channel in 9th and 10th grade, Life would have been breezy..
This guy should have millions of subscribers frr
WOW! Thank You SO Much!!
Damn i finally understand this ty alot
Fantastic video, so easy to grasp. Thank you!
goddamn, what did i do to receive all this help? THANK YOU SO MUCH!!!!!
This is the best educational video and ur channel seems underrated that was better from my physics Mr

Great video
You have saved me on revising to many times 😂
I am a teacher and your videos help out so much! I don’t do any teaching i just make the kids watch these videos 😂😂
Really glad to hear they can help :)
Thank you so much your website is soooo helpful oh my goodness honestly I’m stress revising and it’s helping so much thank you it’s free
You're so welcome!
I have an exam about this tomorrow thanks this helps a lot !
This really helped I have a physics test about this on the 9th october ty
Omg ! Thank you sooooo much ❤️! Finally I understood:)))))) YOU ARE GREAT SIR👍 wish you theeeeee bestttttttt✨✨✨✨✨
beautiful explanation!!!
My igcse physics paper 2 is after couple hours 😭 saved me for real … thank youuuu !!!!!

why are you better at explaining this than all my teachers 🤣
He just is GREAT
Y11 physics mock tmrw pray for me guys😢
How was it!
This chanel is saving me😢🎉
u are the best lifesaver or exam
I’m gonna forget this within an hours
Works like a charm
Clear and concise
it’s kinda easy to tell. parallel definitely more than 1 line comes in mind!😂
Why are larger batteries donominated in volts (i.e. 12v) yet AA batteries are in Milli Amps (2000mAmp). Surely they should both be in volts?
thanks for the lesson....
Thanks!
You're really welcome Jake, thanks for the comment - it really helps the vids get seen :)
this is so helpful thank you
Thank you so much that was helpful
you make science not scary
This was really helpful
Can I ask you a question.
So if voltage increases, does resistance always increase a s well....or does the resistance vary
3 years late, but, yes, the resistance increases
In series and parallel circuits, how can I find whether there will be an increase or decrease in current or potential difference caused by a resistor?
. Do the the same/shared current and pd rules still apply? Thanks
This was explained very well
Tysm👍👍🙏🙏
Thank you this help so much 💗 😅😊
We ain’t studying with this one 😂🔥🔥🔥
thank you toooooo muchhh

My hero 😭👍
Question, which way would be considered backwords or front for the battery , im sorry im not sure and idk if its because i missed someone or if you forgot to say.
It can be anyway
And ur exam is near🎉
This was soooo helpful tyyyyy
Great to hear - thanks for leaving a comment :)
Thank youuuu
You are so helpfull to me
U are the best
shouldnt this be #17? because the previous video is #16
I WAS LOOKING FOR THIS COMMENT LOLLLL

thanks man went from failing aand my teachers said to my parents id fail but i got a 9 this is gonna be ayaan
