Parallel Plate Capacitor Question & Answers October 13, 2022 By WatElectronics This article lists 50 Parallel Plate Capacitor MCQs for engineering students. All the Parallel Plate Capacitor Questions & Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of Parallel Plate Capacitors. In a parallel combination of capacitors, charges on different capacitors are different whereas in a series combination of capacitors charges on different capacitors are the same. The parallel combination of capacitors holds a large charge whereas the series combination of capacitors holds a less charge. In a parallel combination of capacitors, the potential difference across each capacitor is the same whereas in a series combination of capacitors potential difference across each capacitor is different. The equivalent capacitance is larger than the largest individual capacitance of the combination in parallel capacitors. In series capacitors, the equivalent capacitance is smaller than the smallest individual capacitance. If the number of capacitors increases in parallel connection the effective capacitance increases whereas if the number of capacitances increases in series connection the effective capacitance decreases. The three configurations that come under MEMS capacitance configurations are; parallel plate, lateral comb capacitance, and transverse comb capacitance. Capacitive technology allows the measurement of different physical parameters such as vibration, shock products, and seismic products. 1).
