Explanation Write the expression for potential difference between two points. Δ V = V f − V i = − ∫ r i r f E → ⋅ d r → (I) Here, V f is the final point, V i is the initial point, E → is the electric field. If the path is parallel to the electric field chosen then final point will be the negative charge plate and the initial point will be the positive charge plate. Thus, Δ V = V f − V i = V − − V + (II) Write the expression for voltage across the capacitor

Dielectric Constant Of Water

Water constitutes about 70% of earth. Some important distinguishing properties of water are high molar concentration, small dissociation constant and high dielectric constant.

Electrostatic Potential and Capacitance

An electrostatic force is a force caused by stationary electric charges /fields. The electrostatic force is caused by the transfer of electrons in conducting materials. Coulomb’s law determines the amount of force between two stationary, charged particle…

Students have asked these similar questions

A uniform electric field of magnitude 357 N/C pointing in the positive x-direction acts on an electron, which is initially at rest. The electron has moved 3.60 cm. a) What is the work done by the field on the electron? b) What is the change in potential energy associated with the electron? c) What is the velocity of the electron?

A uniform electric field of 250 V/m points in the +x direction. (a) How much work is done by the electric field in moving an electron 50.0 cm? (B) what is the change in the electrons potentional energy? (C) if the election starts from rest, what is its final velocity?

a) Will the electric field strength, E, between two parallel conducting plates exceed the breakdown strength for air (3·106 Vm) if the plates are separated by 2.3 mm and a potential difference of 4800 V is applied? Determine this by calculating the electric field strength between two parallel conducting plates. b) How close together can the plates be with this applied voltage before the air breaks down?
