GCSE Physics Revision "Resistors"

In this video, we continue looking at resistance. We explore resistors. First we look at why we might use a resistor in a circuit, then we look at what is meant by an ohmic conductor. This is critical stuff so expect to see it in your exam.
This video is based on the AQA spec. If you are following a different exam board then you should check your specification. The Amazon link above is an affiliate link.

I was so frustrated with my notes I was ready to cry, this video really helped now I finally understand this thing so thanks

[@fruitpunch3675]

Miss Bad me😔

[@egecr9948]

I want to give huge props to this guy. I never listened at school and only realized this thing might affect my future a month before. I stayed up until 4 am some days and managed to get an 8 in biology 7 in chemistry and 9 in physics.

[@user-qi1jf7io9f]

how did u revise plsss what methods did u use??????/

[@nasteha.9963]

how

[@YousafMannaf]

also learn things like independent , dependent and controlled variable meanings as they are bound to give u a few marks, those marks could be a difference between an 8 or 9.

what if the temperature wasn’t constant in an ohmic conductor? what would the graph look like?

can you please do dissipation of energy?

[@naimesiddique268]

why does he look like that guy in every highschool tv series which every aunty wants to date with :)

[@chewypiano7194]

Is this the same as the required practical?

[@chewypiano7194]

Hi Sir. When you increased the current, would you have to use a variable resistor at 3:20? If so is that not the same thing as the required practical?

[@s.r5394]

if you use a resistor to decrease the current flowing in a circuit would that mean the resistor would require more energy to make the same amount of current flow than the power source can supply, so instead the total current is decreased ?

[@lilytemple971]

He’s got his blazer off ladies!!! (And gentlemen )

[@MRJoKeR-ri2fp]

Are current and resistance inversely proportional??????

[@joshuacarpenter4875]

Are current and resistance inversely proportional?

[@Freesciencelessons]

Yes as long as the potential difference does not change.

[@MotivvETV_1]

3:17 Why is the resistance 100ohms if 0/0 is not 100

[@davodshah8869]

Just a couple hours till paper 1 now

[@jaffryjaman4951]

if I is directly proportional to V , does it mean that I = k(V)?
This question may seem as irrelevant, but is (k)in this context the resistance?
Sir, Do we have to know how to solve direct and indirect proportions for this Science 9-1 specification

[@kurtisgibson2929]

You're right but you don't need to know it

[@MohammedHussain-ss6kj]

wtf is a varible resistor

[@Hellothere-zs3tt]

a component in a circuit that is able to change the resistance

[@fireemperorzuko8756]

A component that can change its own resistance, making it higher or lower and is very useful e.g. can make a light brighter or dimmer
