CAPACITANCEDC CircuitsExample 1: Find the capacitance of a capacitor that stores 8 C of charge at 4 V.CQVC84C2FExample 2: What is the charge taken on by a 5F capacitor at 2 volts?QC VQ(5F) (2V)Q10CExample 3: What is the capacitance if the area of a two plate mica capacitor is 0.0050 m2 andthe separation between the plates is 0.04 m? The dielectric constant for micais 7.CKAd(8.85 x 1012)C70.00500.04(8.85 x 1012)C7.74 x 1012FC7.74 pFTypesofCapacitorsAll commercial capacitors are named according to their dielectrics. The most common are air,mica, paper, and ceramic capacitors, plus the electrolytic type. These types of capacitors arecompared in Table 1.ES-03 Page 12 Rev. 0
