@mfb, I agree. But in the book the answer given for only heat dissipation in capacitor. They have not considered the dissipation in battery. I think they have neglected this fraction of heat lost. But strictly speaking one has to consider. Am I right?
Capacitor connected to a battery of certain internal resistance. If it is asked to calculate what is power dissipated as heat, Does -the voltage across capacitor X current through capacitor- gives heat dissipated or should we add heat dissipated in battery by considering its internal resistance.
A spring is made to oscillate in between a horse shoe magnet. What are things we can study? How does it compares with a pendulum (bob swinging) swinging? Please explain. I wish to do a small project.
large number of magnets attached to a fixed non magnetic circular ring. Another non magnetic smaller radius ring with equal number of magnets is taken. Here magnets are attached such a way that like polls of the magnets of bigger and smaller rings are facing each other. Due to repulsive force...
Orbital Angular momentum quantum number of an electron in its ground state - s - state is zero, l = 0. That means in S - state atom do not have orbital angular momentum. If it is not, then is electron stop orbiting round the nucleus? How to explain this aspect? Or wether we have to abndon the...
How to know whether capacitors are in series or parallel in a circuit which contain many capacitors which are connected in tricky ways. Any thumb rule is there?
