i hope everyone here passes their gcses 💪🤞

POV your here because you have a physics exam tomorrow and you know absolutely nothing about this because your physics teacher is awful and spends the whole lesson giving u a geography lesson on where she is from. No just me ok

[sheilabirling]

here on the day before physics paper 1 2024!

[kazza_]

not gonna lie for chemistry i managed to learn titrations, fuel cells and electrolysis in under 15 minutes. This channel is pretty pog

[speedycrax]

Studying this in online school. Drop a reply if relatable.

[HUDDZINO]

Yo guys whos here before the physics 2023 Paper 1 🙏🏿

[gracie]

POV:Your teacher sent you this link :)

[shakeelshahul]

thank u so much really helped me for my unit test.

[Idkwhaturupto]

The best video I’ve watched in a while tysm

[AbhayHero]

i want your channel to grow but if i share it with my firends then they will be as smart as me and i dont want that

[hamsss]

thank you so much really helped me for my preboards

[dragonkebab]

Doesn't using high voltage also increase the current passing through the grid which will still cause energy loss?

[liiiyahj]

Idk anything abt physics but this is saving me😮‍💨 Good luck for Thursday 🙏🏽

[Yuna-rjwz]

here for my physics in the morning cuz my teacher can’t teach anything

[JetGuy]

Does the step-up transformer reduce the current, or does increasing the potential difference decrease the current?

[aster_]

This explains why my country, South Africa, has so much loadshedding ig 😭

[lucasgraham]

Cognition should change to a gaming channel

[potatoestate]

Increased voltage so less heat / power / energy loss
Current is low obviously
Later low voltage low so appliances not damaged etc
Current is high

[annabel]

did i j unlike this only bc my school sent it to YES
