We are required to explain the change in the electric potential in a parallel plate capacitor.

Electric field:

$\overline{){\mathbf{E}}{\mathbf{=}}{\mathbf{-}}\frac{\mathbf{\u2206}\mathbf{V}}{\mathbf{\u2206}\mathbf{x}}}$

The electric field in parallel plate capacitors:

$\overline{){\mathbf{E}}{\mathbf{=}}\frac{\mathbf{\sigma}}{{\mathbf{\epsilon}}_{\mathbf{0}}}}$ σ is the magnitude of the charge on the plates

The electric potential inside a parallel-plate capacitor __________.

decreases inversely with the square of the distance from the negative plate | |

decreases linearly from the negative to the positive plate | |

increases linearly from the negative to the positive plate | |

is constant | |

decreases inversely with distance from the negative plate |
