OK, the monetary value is obviously zero, as it is short-circuited by
the metal. But the enigma is its electrical value as a capacitor. If a
capacitor is connected to a DC source via a resistor to limit the
current, there will be an initial surge of current of a value determined
by the source voltage and the resistance of the circuit, determined by
Mr Ohm. The current will then decay exponentially as the capacitor
charges, providing a back EMF to the source, heading towards an
asymptote of zero (assuming a perfect capacitor), when it is fully
charged. The higher the value of the capacitor, the higher will be the
current after a given time, and the longer will be the decay curve. In
this case, after the given time, the current will be the same as the
initial value, indicating that the value of the capacitor will be
infinity farads because it can never be charged to the source voltage
and the charging current can never decay. :) :)
