1Rath sir's question isnt it subhomoy?
last one for today!
suppose we are charging a capacitor of capacitance C across a potential difference(battery) of V.
Energy stored in capacitor = 12CV2
work done by battery=q.V
but q=CV
so work done = CV2.
where did the rest 50% energy vanish??
we can say that this is due to the energy loss due to i2R losses.
but suppose we use super-conductors and ideal batteries, so there is no R,
the equations still remain the same.
how do u now account for the loss in energy????

49sir, let us think of the case when we sort the two ends of an ideal battery,
since practically no work is done in moving a charge from one terminal to the other, then they must be at same potential.
isn't it so??
then how can we conclude that batteries give constant potential difference??

rath sir's question!!! i also thought of coming nd asking dis one nd get a pink post!!!
39The way you two fight over pink posts is almost like a bunch of 4-year old kids fighting for candy. How sweet indeed.
Now could someone please finish this question?
