Air breaks down and conducts charge as a spark if the electric field magnitude exceeds V/m. Determine the maximum charge that can be stored on an air-filled parallel-plate capacitor with a plate area of . A air-filled parallel-plate capacitor stores charge . Find the potential difference across its plates.

Respuesta :

Answer:

Explanation:

Suppose

Magnitude of Electric Field is E V/m

Area of the cross-section is A

capacitor [tex]C=\frac{\epsilon A}{d}[/tex]

Distance between Area of capacitor is d

Maximum Charge stored is

[tex]Q_{max}=capacitor\times Potential\ Difference[/tex]

[tex]Potential\ Difference=electric\ Field\times distance=E\times d[/tex]

[tex]Q_{max}=C\times Ed=CEd[/tex]

[tex]Q_{max}=\frac{\epsilon _0A}{d}\times Ed[/tex]

[tex]Q_{max}=\epsilon _0AE[/tex]

 

The potential difference is the ratio of charge and voltage. The potential difference across its plates will be [tex]\rm V= \frac{Qd}{\epsilon_0 A}[/tex].

What is a parallel plate capacitor?

It is a type capacitor is in which two metal plates arranged in such a way so that they are connected in parallel and have some distance between them.

A dielectric medium is must in between these plates.help to stop the flow of electric current through it due to its non-conductive nature .

The value of capacitance for the parallel plate capacitor;

[tex]\rm C= \frac{\epsilon_0A}{d} \\\\[/tex]

The maximum value of the charge that the capacitor can store is given by;

[tex]\rm Q_{max}= C V \\\\ V = \frac{Q}{C} \\\\ \ V = \frac{Q}{\rm \frac{\epsilon_0A}{d} \\\\} \\\\[/tex]

[tex]\rm V= \frac{Qd}{\epsilon_0 A}[/tex]

Hence the potential difference across its plates will be [tex]\rm V= \frac{Qd}{\epsilon_0 A}[/tex].
