How is a mica capacitor constructed
Did you know?
Mica has been used as a capacitor dielectric since the mid-19th century. William Dubilier invented a small mica capacitor in 1909 which was used in decoupling applications. They were put into large scale commercial production to meet military requirements in World War I. Mica is less prone to crack under mechanical shock than glass, a useful property for equipment subject to shellfire. Like glass, mica has a substantially higher permittivity than paper so capacitors can be made smaller… WebA parallel-plate air capacitor is made by using two plates .016 m 2, spaced 4.7 cm apart. It is connected to a 12 − V battery. (a) What is the capacitance? (b) What is the charge on each plate? 6. The dielectric of a parallel plate capacitor is to be constructed from mica (K = 6.2). The area of each plate is 0.5 m 2. a.
