Deadly_king:
You are welcome :)

Glad to have been able to clear your doubts  ;)

Thanks Asif  :D

i have a problem on O/N 2004 paper 2
its on Q6b (ii) & c

S.M.A.T:
b ii)Potential difference acrooss C&R are same as emf(because of parallel connection)

From the graph:
when v=2V
current in R=1.3A
current in C=0.75A
therefore,current in the battery+1.3+0.75=2.05A
c)The current is same in both R&C as they are connected in series.But the potential difference across C is higher than R.Since power=VI,therefore component c will dissipate thermal energy at a greater rate

Greed444:
many thanks asif! :D

S.M.A.T:
U WELCOME ;D
