Question

Which expression gives the capacitance of the reference parallel plate capacitor without a dielectric?

विकल्प

• \[C_0=\frac{V_0}{Q}=\frac{d}{\varepsilon_0A}\]

• \[C_0=\frac{\varepsilon_0d}{A}\]

• \[C_0=\frac{Qd}{\varepsilon_0A}\]

• \[C_0=\frac{Q}{V_0}=\frac{\varepsilon_0A}{d}\]

Answer 1

Capacitance is charge divided by potential difference. For parallel plates without a dielectric, this gives \[C_0=\varepsilon_0A/d\].
