oohhh rytt!! so we will take (energy under both graphs) - (energy ender lower graph) to get (energy b/w the graphs) which will be the energy lost??? is that wat is happening? -

Heyy :) would any of u happen to have complete nuclear physics notes? plz upload them if u can :) -
Physics: Post your doubts here!
but shouldn't the energy expended be below the lower graph?? because the one between the two graphs is recovered? -

oh okay thanks for the heads up ! 0-0 Best of Luck -.- -
Physics: Post your doubts here!
ok but wat about the last part of the question... how do we know that the circuit can be used to store energy in A? i mean the marking scheme does say that because power in B is greater than energy dissipated per unit time but i don;t get it.... can u explain it to me please? -
