Question

Consider a parallel-plate capacitor with a dielectric fully inserted between the plates. Describe the potential difference across the plates in terms of the surface charge density $\sigma$ , polarisation surface charge density $\sigma_p$ , and permittivity $\varepsilon_0$ . Which equation correctly represents this relationship?

A

V = $\frac{\sigma - \sigma_p}{\varepsilon_0}$ d

B

V = $\frac{\sigma}{\varepsilon_0}$ d

C

V = $\frac{\sigma + \sigma_p}{\varepsilon_0}$ d

D

V = $\frac{\sigma}{\varepsilon_0}$ (d + \sigma_p)

Accepted Answer

V = $ \frac{\sigma - \sigma_p}{\varepsilon_0} $ d

Answer

V = $ \frac{\sigma}{\varepsilon_0} $ d

Answer

V = $ \frac{\sigma + \sigma_p}{\varepsilon_0} $ d

Answer

V = $ \frac{\sigma}{\varepsilon_0} $ (d + \sigma_p)
