the instantaneous current direction with the insulation rod connecting the metal ball two electroscope is from A to B
So the actual electronic (negative charge) from B to A.A has been a part of electronic, charged to reduce; B lost some electrons, is positively charged. On the surface (false) is charged from A to B, is actually electronic (negative charge) from B to A. the positively charged nucleus is unable to move.
Yes, the direction of the current is from A to B.. The electrons are negatively charged and are able to moveThe positively charged A, is actually a lack of A electronic B; not charged, is positive and negative charge balance B itself. Connected with copper with insulated handles, in order to achieve a uniform charge on B, a part of electrons to the A transfer.
But the direction of the current is specified in the same direction as that of the positive charge, in the opposite direction of the direction of the negative chargeThe negatively charged electrons move from B to A, so the current is from A to B.
