Question

What is the potential difference across the plates in the reference state without a dielectric?

Options

• \[V_0=\frac{E_0}{d}\]

• \[V_0=E_0d\]

• \[V_0=\frac{Q}{E_0}\]

• \[V_0=E_0A\]

Answer 1

For a uniform field between plates separated by distance \[d\], the potential difference is the field multiplied by the separation. Thus, \[V_0=E_0d\].
