Two parallel plates, each having area A 3676cm are connected to the terminals of a battery of voltage V, 6 V A as shown. The plates are separated by a distance d 0.42cm. You may assume (contrary to the drawing) that the separation between the plates is small compared to a linear dimension of the plate + A 1) What is C, the capacitance of this parallel plate capacitor? 7.746E-4 uF Submit 2) What is Q, the charge stored on...
6. You have a parallel-plate capacitor made of two circular metal plates. The radius of each plate is 2 cm and they are separated by a distance of 1 mm. (a) What is the capacitance of this capacitor? (b) If you hook this capacitor up to a 9-V battery, how much energy will be stored in the capacitor? (c) If the 9-Volt battery has a total capacity of 610 milliAmp-hours, how many of the above capacitors could you charge up...
1. Parallel plates. You have two equal but oppositely charged parallel conducting plates, separated by 10 cm. A voltmeter shows that the potential difference between the plates is 500 V. (a) Which is at a higher potential, the positive or negative plate? (b) How big is the electric field between the plates? (c) You let go of an electron next to the negative plate. How much work does the electric field do in moving the electron to the positive plate?...
what is b plz . Consider a disconnected parallel plate capacitor with area Ao and width --4, 3do. There is a magnitude of charge density g, on each plate. For this problem you may assume the plates are large enough to neglect fringing fields. 3d How much energy is stored in the capacitor?2 z a. For the purpose of simplifying the math, assign this value 3E. A large conducting slab of area A and width do is now placed within...
Two-Part Pricing Problem You can get a maximum of two-percentage points added to your test average without using calculus. Use your knowledge about price-searching firms and two-part pricing to advise the company below. The company has a bar and is trying to decide on the cover charge (if any) and price for each drink. It has done a modest survey to ask customers to classify themselves as light drinkers or heavy drinkers and to indicate the number of drinks they...
Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
