How much charge can be placed on a capacitor with air between the plates before it breaks down if the area of each plate is 4.00

klio [65]

Explanation:

Let us assume that the separation of plate be equal to d and the area of plates is $9 \times 10^{-4} m^{2}$ . As the capacitance of capacitor is given as follows.

C = $\frac{\epsilon_{o}A}{d}$

It is known that the dielectric strength of air is as follows.

E = $3 \times 10^{6} V/m$

Expression for maximum potential difference is that the capacitor can with stand is as follows.

dV = E × d

And, maximum charge that can be placed on the capacitor is as follows.

Q = CV

= $\frac{\epsilon_{o} A}{d} \times E \times d$

= $\epsilon_{o}AE$

= $8.85 \times 10^{-12} \times 3 \times 10^{6} \times 4 \times 10^{-4}$

= $1.062 \times 10^{-8} C$

or, = 10.62 nC

Thus, we can conclude that charge on capacitor is 10.62 nC.

Which of the following statements might be used to defend the Act of 1848

d1i1m1o1n [39]

The Public Health Act of 1848 was the result of advocacy by Edwin Chadwick, in response to the deplorable living conditions of poor urban laborers. Prior to the Act there were no uniform regulations regarding provisions for proper sanitation and clean water in cities where poor workers resided. As a result of the Act's passage, local governmental agencies were tasked with the responsibility for providing proper sanitation in urban communities in England and Wales.
