Fig 01: Direction of Electric Field from the Upper Plate to the Lower Plate
In this setup, the system is charged with positive voltage. The upper plate gets charged with
the positive charges and the lower plate gets charged with negative charges. The direction of
the electric field is from the upper plate to the lower plate as expected since the direction of
an electric field due to a positive charge is always points away from it and the direction of an
electric field due to a negative charge always points towards the negative charge.
, Fig 02: Direction of Electric Field from the Lower Plate to the Upper Plate
The plates are charged with negative voltage this time. The lower plate gets charged with
positive charges and the upper plate gets charged with negative charges and the electric field
points upwards.
