- Chapter 26 A parallel-plate capacitor has plates of area 0.2 m? and a separation of 0.9 cm. A battery charges the plates to a potential difference of 100 V and is then disconnected. A dielectric slab of thickness 9 mm and dielectric constant 2 is then placed symmetrically between the plates. (a) What is the capacitance before the slab is inserted? (b) What is the capacitance with the slab in place? (c) What is the free charge q before the slab is inserted? and (d) What is the free charge q after the slab is inserted? (e) What is the magnitude of the electric field in the space between the plates and dielectric before inserting the dielectric? (f) What is the magnitude of the electric field in the space between the plates and dielectric after inserting the dielectric? (g) With the slab in place, what is the potential difference across the plates?In a lab where you construct a capacitor made of two brass plates with a dielectric between them, if the dielectric does not completely fill the area in between the brass plates, what would be the expected capacitance? Derive an expression for the deliectric constant in terms of the measured capacticance, the area covered by the dielectric, and the remaining area not covered by the dielectric.How would the capacitance of a parallel capacitor change if a dielectric was placed between the plates?
- Capacitance Problem 8: A 0.072 μF capacitor is being held at a potential difference of 466 μV. Part (b) If you measure the size of each plate to be 49 cm2, how far apart are the plates, in micrometers?answer c d ea) A capacitor consists of two parallel metal plates immersed in a high-dielectric liquid, chloro- cyclohexane (e = 30). When the separation of the plates is 1mm, the capacitance is 0.06 F. Initially it is charged, at 500 V. Assume that 0 = 8.85 x 10-12 Fm-1. i) == Use this information to calculate the area of the plates, and the charge and the energy stored. ii) The plates are now pulled apart, to a gap of 1cm. Calculate the voltage it is now at, the energy now stored, and the force required to pull the plates apart.
