Step 1
The area of a circle is given by the formula A = πr^2, where r is the radius of the circle. Given that the radius of each plate is 12 cm, we can calculate the area of each plate as follows: A = π(12 cm)^2 = 144π cm^2. Show more…

A parallel plate capacitor consists of two circular plates each of radius $12 \mathrm{~cm}$ and separated by $5.0 \mathrm{~mm}$. The capacitor is being charged by an external source. The charging is being charged and is equal to $0.15 \mathrm{~A}$. The rate of change of potential difference between the plates will be (A) $8.173 \times 10^{7} \mathrm{~V} / \mathrm{s}$ (B) $7.817 \times 10^{8} \mathrm{~V} / \mathrm{s}$ (C) $1.873 \times 10^{9} \mathrm{~V} / \mathrm{s}$ (D) $3.781 \times 10^{10} \mathrm{~V} / \mathrm{s}$

A parallel-plate capacitor is made of two circular plates, each with a diameter of 2.50x10^-3 m. The plates of this capacitor are separated by a space of 1.40x10^-4 m. Assuming that the capacitor is operating in a vacuum and that the permittivity of a vacuum can be used, determine the capacitance for this arrangement.
