All of AQA Electricity Explained - A Level Physics Revision

[@realchickennuggy]

I'm not even kidding. I used to get 60's and 70's for school exams and after watching your videos I started to understand physics concepts at an unbelievable scale. I managed to get an A* in the final examination! Thank you so much! Please keep uploading videos to help future students!

[@PhysicsOnline]

Great job!

[@frieda1471]

how else did you revise? I’m in year thirteen and really struggling :/

[@deetha1840]

@@frieda1471 I find that teaching is one of the best ways of learning! Teaching your parents, friends or even a stuffed animal! It enables you to word things in a way that is easily understandable and therefore benefit you. You will be able to remember content so much easier as your brain will really be processing the information:)

i have my physics paper 1 exam in a couple of days and this has really helped. electricity has always been my weakest side and i felt kind of lost but after watching this i feel like i can finally pick up the pace in revising this area. thank you so much

Thank you for sharing! This is such a great resource for teachers and tutors too =)

Interesting that despite being an ISC student, I can study from an A level tutor, and still be able to understand the topic with clarity. Nice mind map by the way.

I have been watching your videos throughout the entirety of my A-level Physics course and you have helped me with my understanding so much. Now I'm a week away from Paper 1 and I'm rewatching your videos, whilst going through the CGP guide, because they are so good. Thank you so much for all your hard work to help us out! :)

Amazing, hope they continue to be helpful for you in these last few weeks.

[@natural5546]

@Tjk_ SkaZeRe.m.f stands for electrotmotive force. It is essentially the total electrical energy supplied by the battery sent around the circuit. Units are V. The weird looking E represents e.m.f in the equation and is also the Greek letter known as epsilom. Hope I was able to answer your question.

[@alyasa7617]

Don’t even study physics, just searched “people having breakdowns over a levels” (as it makes me feel better) then this came up

I do AQA physics and we learnt Kirchhoff's laws and was told it would be in the exams

[@eddie6584]

Just gonna add something, for the I-V characteristic graph for the diode, the line won’t starting going up from the origin because diodes have what’s called a threshold voltage meaning a current will only start flowing once the threshold voltage has been reached, for the diode shown in the video, this would be around 0.8 volts.

[@eddie6584]

I’m only doing GCSE’s haha but I’m just a nerd, I don’t know if you actually need to know this for the A-Level but I thought I’d mention it anyway 👍

[@MohammedAhmed-pb9xm]

Hi Sir, Have you got a revision video for aqa particle physics? Thanks for your hard work

Sir, for the last part about resistors and cells in parallel, how does the current and resistance add up and say we connected a lamp in parallel to the circuit drawn, what the current and resistance be.

[@jadea2594]

Hello, how do you derive the length of a wire from the number of turns ( and diameter)

[@PhysicsOnline]

No. of turns x circumference

[@meliasummers6730]

Could you do a video on battery chargers where there is one battery charger and cell in series with opposite terminals connected ? These question always come up .

[@cx11]

Does the symbol you wrote at 21:11 mean anything because whilst its not the right one it looks familiar

[@PhysicsOnline]

It’s similar to an LED, but that would have the arrows pointing away from it.

Would this be good for CIE even tho it's AQA?

[@fuadsalah8286]

check the spec and see if it has the same content

[@thiccteletubby1234]

cant thank u enough bro

[@kallamsamad6736]

You missed out small things that are quite important such as the value a diode will produce current but overall it's good. I wouldn't rely on this video on it's own though.

[@clahrenssgramula4374]

Will this be useful for me if I do As physics but from cie board?

[@PhysicsOnline]

Yes it will

[@nevanmasterson46]

22:06 can someone explain to me why there's no resistance when the pointer is at the left end? surely if it's at the other end the circuit bypasses the resistor and effectively avoids the resistance? i'm not correcting or anything, i'm sure it's right., but i just don't understand why 😔

[@samdicks9146]

The resistance is proportional to the length : R = (resistivity x length)/area . Therefore when l = 0, r = 0, such as there being no resistor. Therefore as V = IR, there is no voltage.
