Your videos are INCREDIBLE! Thank you so much for making them. I'm in an HVAC program in Arizona (I don't even know what GCSE is!), and these have been the best videos I've found online to explain many electric, heat, and energy concepts. I wish my whole curriculum was here! The color coding, the thought behind each video, the organization -- your hard work is apparent, and its result is easier transfer of knowledge. Wow. I'm telling my classmates to use your videos!
I'm 29 and taking a GCSE equivalency exam in combined science (I didn't go to school in the UK) to do my teacher training and this is literally THE BEST SOURCE OF SCIENCE LESSONS on UA-cam. I appreciate your work with all of my heart. Great job!
Cognito is talented man explained everything i probs need to know in gcse about parallel and series circuits in 3 mins bro imagine if i watched him for an hour everyday i would be Einstein
the resistance bit for parallel circuits is proper good, especially the river analogy. As soon as you mention the added loop and that water flows more easily, it instantly just clicks in the brain. Just what i needed. Keep it up my guy:)
Thanks. I am learning welding remotely. Very big help towards the exams. You know how to explain things so I could understand and your voice is very relaxing which helps too.
Question: total resistance of parallel is 1/R1 + 1/R2 + 1/R3... and so on, so mathematically, why does the total, i.e. the sum, decrease the more resistors there are?
The resistances are added as reciprocals, its like rather than adding them normally, they are flipped over as fractions and added and even though the result is bigger than the fractions, its is flipped again making it smaller than the original numbers eg if r1=2, r2=3 1/rt = 1/2+1/3 1/rt = 5/6 rt = 6/5 or 1.67 It reduces because it is flipped and then added and flipped back, hope this helped
But it says the resistance increases when I add more components not loops . If you increase the number of components on the same loop surely the resistance of the circuit must increase.
I have a question. If there's 9V from the cell and 1st branch has 2 bulbs 2nd branch has one buzzer, Will each branch still get equally 9V? If yes, it means that no matter what, each branch has equal voltage?
You will probably not reply in time if u dont its fine but say in the parallel circuit powered by a 3 volt battery and you have two leds wired one has a higher resistance then the other one will both leds still receive 3 volts
hello cognito really apreciate you vids but i didnt quite understand about the resistance in parallel circuit.can u explain plz coz its important for exam style questions.

Very underrated channel
Aha thanks Luca! Really appreciate the support :))
Trueeeee, I hope they get more attention!

That river flow analogy for the Resistance in Parallel Circuits is so smart! Thank you so much for your help!
Oh my days I think I finally understand. That analogy was spectacular.
frr fsl dosent explain this properly like cognito

GCSE Is Uk high school curriculum
Sometimes middle school

How did it go?

@@fouadmajidi2568 she probably didnt finish :/
@@fouadmajidi2568 I got an A. From English as well.
@@Sol4rOnYt I got 2 A’s and did my PGCE. I’m starting my third postgrad in September so it’s not going bad at all :)
This channel deserves at least 5 million subscribers
Ah thanks Fun Facts, really appreciate it 🤩
Or more
Cognito is talented man explained everything i probs need to know in gcse about parallel and series circuits in 3 mins bro imagine if i watched him for an hour everyday i would be Einstein
Last day before my GCSE physics, whish me luck
good luck chungus I'm here with you too
@@leeyam2520 goodluck to you to
@@bigchungus3337 thank you big chungus
how did it go?
you make everything so easy to understand i love your videos so much especially the examples for complex ideas you’re the best channel ever!!
Super underrated and just too good to be real! Sir you just saved me at the last minute preparation of National Finals! Thanks alot😊
I understand this dude more than my teacher💀
WHY IS THIS CHANNEL SO UNDERRATED?????:(
You are just the best. I can’t understand the open uni but I can understand a man on UA-cam. ❤
my exam is in an hour so im binging all your videos *cries* they actually saved my life fr *cries some more*
the resistance bit for parallel circuits is proper good, especially the river analogy. As soon as you mention the added loop and that water flows more easily, it instantly just clicks in the brain. Just what i needed. Keep it up my guy:)
Thanks for providing the examples and analogies, they helped me understand the concept much better.

Ah thanks Ta Dum! glad you're enjoying them 😊
Thank You I finally understand what the resistance is for parallel circuits. :D
he deserves more love and subs he's too good
Thank you very much Evan!!
Super underrated! Love your videos Sir! From Pakistan.
Bro I’m watching these vids on electricity at 1.5x speed cause I have an exam and I can’t remember 😭it’s in 30 mins this vids are helping sm
Your amazing and SO underrated, you are the source of my good grades! Thank you, I hope you feel appreciated!
Helped me in my exam, thx sir i wish you had a million subs
this series means that i am no longer cooked for my exam tommorow , thank you so much
U got a new subscriber
Made it sooo easy to understand! Thank you so much!!!!
POV your exam is in 2hours and you have 3 topics to complete
I think this channel is a few million suscribers short. If you consider the great content on it.
Ah thank you, we really appreciate it 😊
I LOVE THIS CHANNEL
Very good sir you are great I had my science exam and I hope it will be good now
Take a bow
commenting to help the algorithm, your channel helps me pass my exams
Thank you so much this is helping me for my exam a lot!
ive been watching ur vids for the last 3 hours and ive learnt more off of here than actual school thank you
M a r y
@@milliesotheraccount yes we stan mary
@@burpqueen11 y e s
the only channel that helps me in science and math for real
I learn better in 3min videos than many hrs of lectures
goat for a reason
Very good explanation about the resistance
i truly love this account
Ur video helped me the most then others ty very much!!
Your video is super helpful! I have a test on this tomorrow .. you helped me a lot
Brother ur the best I have moc thank exam tmrw and this helps
hey, i was just wondering if you could do a vid on Flemmings left hand method
I would actually fail my exams if it wasnt for this channel 😊
Question: total resistance of parallel is 1/R1 + 1/R2 + 1/R3... and so on, so mathematically, why does the total, i.e. the sum, decrease the more resistors there are?
The resistances are added as reciprocals, its like rather than adding them normally, they are flipped over as fractions and added and even though the result is bigger than the fractions, its is flipped again making it smaller than the original numbers
eg if r1=2, r2=3
1/rt = 1/2+1/3
1/rt = 5/6
rt = 6/5 or 1.67
It reduces because it is flipped and then added and flipped back, hope this helped
But it says the resistance increases when I add more components not loops . If you increase the number of components on the same loop surely the resistance of the circuit must increase.
Can you do A levels too plz it would be very helpful
@Cognito you should atleast have 2 million subscribers!!
This was really helpful ❤ thanks 😊
for a series circuit how is the current the same at every point where resistance reduces current and different components have different resistance?
I have a question.
If there's 9V from the cell and
1st branch has 2 bulbs
2nd branch has one buzzer,
Will each branch still get equally 9V?
If yes, it means that no matter what, each branch has equal voltage?
first branch will work as a series circuit then and both the lights will share the voltage
Why is he so helpful oh my god i literally cannot
Thank you so so so so much,this was very informative. But can you Pls make a video about tectonic plates???
thanks teacher🙂
your channel is really good loved it!!
here for my igcse exam's in oct/nov thanks for the help
Get this man some subscribers.
Amazing work
0:35 that's not true if the cell stops working then the circuit is intact
I love this channel!!!♥️ Your videos are always useful. Thank you!!!
Aw thanks m g, glad you like them 😊
few hours left for my exam, tryna cover the entire thing before the dooms day😭
Thank you
awesome vid thanks a lot
You simplify difficult concepts that I find hard to grasp. Thank you so much for your hard work!
You will probably not reply in time if u dont its fine but say in the parallel circuit powered by a 3 volt battery and you have two leds wired one has a higher resistance then the other one will both leds still receive 3 volts
yes
Good job you are correct
Thank you so much😘😘
This was a masive help for me as i am in high school. This chanel is a masive influence on my life thank you 🙏
Thanks JPINDER we're really glad you're finding them useful 🙌
TOOO GOOOOD!!!!!!
we watched already
liked and suscribed! great video
Thanks Amina - really appreciate the support!
hello cognito really apreciate you vids but i didnt quite understand about the resistance in parallel circuit.can u explain plz coz its important for exam style questions.
Not me getting this set a few years ago as a year 8 😅
so do you add resistance??
Thank u!
sir i want notes that i wrote in video
thank u this was great help sir
Thanks W vid
You're a very good channel. Thanks alot.
ur vids r awesome dont stop pls
videos help a ton, thanks dude.
this is very underrated, I find it so useful, everything I didn’t understand during class I underst@d in a few minutes here, it deserves more subs 😄😄
Thanks Tanya, glad you found it helpful 👍
❤❤❤❤❤
Very helpful, thanks.
thank you man
Please make more videos! Yours are very helpful 😊👍👍👍📚📓📒📃📘📗📖
Absolute lifesaver tysm
You sound like jack whitehall
YAYAYA THANKS ^V^
What is the reason??why voltage remain same in parallel circuits??
great videos
Thank u sooo much i subed it rlly helped me
I still can’t understand what resistance mean??
Oh btw im 9
Y
meh
Hi
Awesome stuff thanks
my exam is in 1 ½ hr guysss 😭🫡
