Silver Electrodes

Hello,

I fabricated interdigital capacitors using silver as the primary metal for
the electrodes.  I applied a DC voltage across the electrodes and they began
to melt/burn at about 25 Volts.  I fabricated more capacitors using gold as
the primary metal and performed the same test up to 100V, and the electrodes
were not affected by the high voltage.  Does anyone know why the silver can
not withstand the high voltage and why the gold can?  Is there a
metallurgist out there that can explain this phenomena?

Thanks,
Tony
