Steinberg) Organization: University of California, Berkeley Lines: 9 A clear way of seeing that this calculation is faulty without even bothering to complain about the impossibility of zero-resistance and zero-inductance (it seems to me that the same error could be made as easily with a finite R) is to ask why you multiply 1C by 1V. When you start moving that coulomb, there is not yet 1 volt of potential on the other side. It ends up looking like a triangle with base 1C and height 1V, whose area is of course 1/2. By setting R=0, you are simply taking lim t-->0 of an integral, but that doesn't give you the right to drop the integral and just multiply your final values.
