Capacitors vary in shape and size, but the basic configuration is two conductors carrying equal but opposite charges (Figure 5. The quantitiy capacitance C is related to the charge on the electrodes (+Q on one and −Q on the other) and the voltage di erence across the capacitor by C = Q=VC Capacitance is a purely geometric quantity.

For example, for two planar parallel This document summarizes a lecture on capacitors and inductors. If A is large and d is small, the plates are effectively infinite planes, and the E LECTURE NOTES B. g. Besides resistors, capacitors are the most common electrical components. They’re everywhere—but we won’t go into applications much. Anusha, AP/ECE Department of Electronics and Communication Engineering MALLA REDDYCOLLEGE OF ENGINEERING& TECHNOLOGY (Autonomous Institution – UGC, Govt. Digital Electronics. difference of the capacitor as “capacitance”. Take the distance between the plates to be 0.

Take Gaussian surface as cylinder between conductors (E=0 inside conductors). Make an accurate drawing of the capacitor current. Prof. V. A capacitor is used to store charge and energy. (radio frequency) power circuits (PDF - 1. Capacitors A capacitor is simply two pieces of metal near each other, separated by an insulator or air. Lecture Notes. C q dq dW dU v dq ⋅ = = ⋅ = C Q q dq C W dW W Q 2 1 2 0 0 = ∫ = ∫ ⋅ = Work to charge a capacitor: - Work done by the electric field on the charge when the capacitor discharges. Notes for Lecture 24 are not available. TECH (IVYEAR–I SEM) (2018-19) Prepared by Dr. " To get an idea of the magnitude of the unit Farad, find how large a parallel plate capacitor must be in order to have a capacitance of one Farad. This distinguishes it from classical electrical engineering as it uses active devices to control electron flow by amplification and rectification rather than The behavior of the capacitor is based on the properties of the electric field created in a dielectric (non-conductor) placed between two conductors. Therefore the notes may contain errors and we are open to corrections, feedback and comments, especially from the students - The electric potential energy stored in a charged capacitor is equal to the amount of work required to charge it. Later, we do the same for inductors. of India) Recognized under 2(f) and 12 (B) of UGC ACT 1956 Electronics Electronics comprises the physics, engineering, technology and applications that deal with the emission, flow and control of electrons in vacuum and matter. 4 %Çì ¢ 7 0 obj > stream xœ­SM Ô0 ½çWø˜"M° ÄŽ9 {qY4 ÄiøZ±3«aáÿãôcÉ =ì Vj_Sçùõ½ú ˜ˆ û¹ Ã1 oðí>œC¦Ú—Ž ¨‚ ·aýú=|€S8òœ v^LýŽ0#rä—™— ^ß…k?Ïa`î ¶XÈ»:1c2 ‡è‡ øá,-å~ÌÒG|8ÂË}ïHÀÕÕì¿: Kéj@-1× E UUØ ÃÇønrõU Rü2¹d.
