Physics (Need help ASAP)

[Netherdrake]

I have only got few days for Physics
I really suck in Electricity section
I have not touched ATP yet!

Tips and Help PLEASE!
Now i go solve a lot of past papers

i think this is all you need for o level physics , this story explains explains everything
Think of current as a lazy dude, he's always looking for easier paths ,this explains the fact that more current flows in the branch with lower resistance
Think of resistance as the jerk who is always a hindrance for current, he is always trying to stop current.
Think of volt or e.m.f as currents bossy friend who is always pushing current and having his own way , so when there is a bigger obstacle (resistance) comes in front of current ,his bossy friend the volt pushes him harder .explaining the fact that Resistance is directly proportional to E.m.f .
Remember this and you will find bijli , shijli easy .

hope this helps ''spawn of death wing ''

Okay thanks m8.
I know about resistance and that EMF stuff.
But calculating them is the real problem

 

[Alpha Destro]

Bruhh that's the easy part you just need to know the relationships between resistance .p.d ,emf,current,power and energy which i can bet you already know ,whats important is knowing how current ,voltage and resistance behave and differ in different parts of a circuit u need to know things like current is different in every branch of a circuit but voltage is the same usually the examiner tries to set in questions involving these things mixed with calculations to confuse you .

Hey Buddy Dont Worry Just For ATP Practice last 5 years Question & u are done
But Pay more attention towards the graph , micro meter , reflection,magnetism,Speed time graph

9.6 round off to 10 so X= 10

Its difficult
Em trying........

2013, 2014 paper i faced this kinda probs am waiting

My Question is Wrong Check I said Fe2
but its Fe 2+
If Fe is 2+ and SO4 2- then the formula would be FeSO4
sorry i just confused you
