Determine the area of the parallel plate capacitor in the air if the capacitance is 25 nF and the separation between the plates is 0.04m. Solution: Given: Capacitance = 25 nF, Distance d = 0.04 m, Relative permittivity k = 1, ϵ o = 8.854 × 10 −12 F/m. The parallel plate capacitor formula is expressed by,
A simple capacitor is the parallel plate capacitor, represented in Figure 1. The plates have an area Aand are separated by a distance dwith a dielectric ( ) in between. The plates carry charges +Qand Q, respectively, on their surfaces. The capacitance of the parallel plate capacitor is given by C= C 0 = Q V 0 = 0A d (1) 1-+-+-+-+-+-+
A 1-farad capacitor would be able to store 1 coulomb (a very large amount of charge) with the application of only 1 volt. One farad is, thus, a very large capacitance. Typical capacitors range from fractions of a picofarad (1pF = 10 − 12F) to millifarads (1mF = 10 − 3F). Figure 19.5.3 shows some common capacitors.
The purpose of this lab was to fully understand the concept of a parallel plate capacitor and. measure the capacitance value. Background.
