Parallel Plates Electric Potential Difference using an Integral

In a parallel plate capacitor with a positively charged top plate and a negatively charged bottom plate, what is the direction of the electric field between the plates?

• Upward, from the negative plate to the positive plate.

• Downward, from the positive plate to the negative plate.

• Horizontally, parallel to the plates.

• The direction varies depending on the location between the plates.

What is the general equation for the electric potential difference (ΔV) between two parallel plates separated by a distance 'd' with a uniform electric field 'E' between them, when moving in the direction of the electric field?

• ΔV = Ed

• ΔV = E/d

• ΔV = -Ed

• ΔV = -E/d

What does the negative sign in the equation ΔV = -Ed signify regarding the electric field and electric potential?

• The electric field points in the direction of increasing potential.

• The electric field points in the direction of decreasing potential.

• The electric potential is always negative.

• The electric field is always negative.

If a charge moves in the same direction as a uniform electric field, what happens to its electric potential difference (ΔV)?

• It goes through a positive ΔV.

• It goes through a negative ΔV.

• It remains unchanged.

• It depends on the magnitude of the charge.
