question. What is true about electric field between the
parallel pate capacitors? Choose from below
A. Electric field starts from the negative plate and ends at
the positive plate.
B. Electric field starts from the positive plate and end at the
negative plate.
C. Electric field could start from positive or negative plate, it
does not matter.
D. Electrid field starts from the postive plate, only if the
positive plate is on the left side.
. High PE 0 The electric potential difference AV between points A and B is defined as the change in the potential energy per unit charge. (note that "change" means "final value minus the initial value") E E Ax B 162 400 AV=VB-VA = APE/q Low PE J Plate of the capacitor Av APE=-WAB = -qExAx A special case of Potential difference: occurs when there is a uniform electric field. . AV=-E, 4x) Source dependant term Although the electric field is constant, . the electrical potential is higher near the positive plate and lower near the negative plate. For a positive charge: PE is higher near the positive plate and lower near the negative plate → A positive charge will move towards negative plate. For a negative charge, the electric potential energy is higher near the negative plate → A negative charge will move towards the positive plate.
