SUMMARY
A capacitor can indeed function as a static electricity generator, as demonstrated in early experiments with devices like the Leyden jar and electrophorus. When a capacitor is charged and one terminal is grounded, the remaining charge can create a detectable net positive charge, which can influence a pith ball. However, the voltage of the capacitor limits the maximum charge that can be transferred to the pith ball, meaning that a larger capacitor at the same voltage will not increase the charge on the ball beyond that voltage.
