This taught me more than my teacher did in a whole year!

Thanks for the video !

[rumiachowdhury]

*How do I learn more in 10 min vid of u than I do from a whole year w my physic teacher*

[thedaphnegale]

thank you for helping me !! a girl sits next to me in science and she’s quite the distraction. thanks queen

[elenicosp]

im so thankful for your videos they honestly save me, my class has 36 people in it and it’s so hard to get 1-1 support when you don’t understand a concept, so these videos are great when you feel behind with the work, thanks!

[deano]

electricity has been turned from a disaster into something i now fluently understand

[okuyasunijimura]

You lady just saved my GSCEs, and that’s NOT easy as I am

[cyrilamantlediphale]

Nice... I like how you just sum up everything

[stupidpatato]

for the past 2 weeks ive been going through ur videos & it helps to revise for the mocks a day before

[edwardwinters]

I had to retake my exam and I got 27 more points than last time. THANK YOU!!!!

[dominicaeliasova]

Thanks a million! You have really helped me with my GCSE'S :)

[honestlyitsafunnystory]

You even have captions for your video, you are an amazing human <3

[rowanHelm]

Thank you so much, my physics mock is tomorrow and so im currently watching all your physics videos and making flashcards, you have saved my results

[alexflorance]

maybe you could explain the transformer bit a bit better. maybe say why there is less energy loss? and about the change in current? thanks for the video! I'm here aged 18 to revise for my BMAT exam! its very helpful

[franh]

I still don't understand how current splits and voltage splits in parallel and circuit. like does it split equally? Does it drop one unit off? I don't understand

[SeriousJohnnyDay]

how did whoever wrote the subtitles possibly think she was saying anteater instead of ammeter??? lmao

[aminur]

Who else has Physic P1 MOC tmr and is completely lost?

[itsmesb]

Thank you so much i genuinely can’t thank you enough for these videos they are so amazing.

[caiwilliams]

so useful to have exactly what you need to know for gcse in each video, this is what’s gonna get me my gcses

(Circuit symbols)

Parallel connected

Charge -value for electricity flowing in circuit
Current flow of electrons
Potential difference- pushes current around
Resistance slows down current

Potential diffeeent graphs

Thermistor central heating

LDR-street lights

Current same in series
Potential difference . Split across components
Resistive total is R1+R2

Parral split

Main electricity 50HZ 230v

Power stations to step up transformer to stop down to houses


Step up transformer low voltage to high

Step down high to low voltage
