# exterior electric field on a capacitor

Has it been observed that charged high capacitance capacitors do generate a strong positive electrostatic charge on their exterior insulating surfaces?

Has it been observed that charged high capacitance capacitors attract exterior negative electrostatic charges to their exterior insulated surfaces?

One of the points of a capacitor is that it minimizes the electric field outside of the capacitor while storing charge. – Jerry Schirmer Jul 17 '13 at 17:43
This effect could be happening at the edges of the capacitor plates where the field doesn't cancel out. – udiboy1209 Jul 17 '13 at 17:49
