I agree with u that there is no such thing as a wire with zero resistance, in practice. However, I just want to consider the problem in theorem, that means there is no resistance. I wonder if the energy come out from the circuit as an electromagnetics wave. Please take a serious look at it...
suppose that the wire is made from super conductor material, so its resistant is zero, or we can have sth like that. Generally, i just want to consider the problem in theorem, so what is the fault?
A capacity(C) connects directly to a constant source(E); total resistant is zero. When the capacity has been charged already, it has energy :1/2CE^2. The work done by the source
is CE^2. Comparing two of them leads to an error of the energy conservation equation. What's wrong with it?
When...
