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. :) :) Brian Brian Ellis wrote: > On http://stevezeva.homestead.com/files/c46.JPG there is an 'orrible > photo of a ceramic capacitor.
