Capacitance of a tube

The monotonic charge density consists of a constant term plus the inverse square-root function that is the form of the exact solution for the conducting strip in two dimensions. An asymptotic formula is derived for the capacitance of a long, thin tube.

8.4: Energy Stored in a Capacitor

In a cardiac emergency, a portable electronic device known as an automated external defibrillator (AED) can be a lifesaver. A defibrillator (Figure (PageIndex{2})) delivers a large charge in a short burst, or a shock, to a person''s heart to correct abnormal heart rhythm (an arrhythmia). A heart attack can arise from the onset of fast, irregular beating of the heart—called cardiac or

6.1.2: Capacitance and Capacitors

Placing capacitors in parallel increases overall plate area, and thus increases capacitance, as indicated by Equation ref{8.4}. Therefore capacitors in parallel add in value, behaving like resistors in series. In contrast, when capacitors are placed in series, it is as if the plate distance has increased, thus decreasing capacitance. Therefore

Formula and Equations For Capacitor and Capacitance

The following formulas and equations can be used to calculate the capacitance and related quantities of different shapes of capacitors as follow. The capacitance is the amount of charge stored in a capacitor per volt of potential between its plates. Capacitance can be calculated when charge Q & voltage V of the capacitor are known: C = Q/V.

When a parallel-plate capacitor is filled with a dielectric, the capacitance is increased by the factor begin{equation} label{Eq:II:10:11} kappa=1+chi, end{equation} which is a property of the material. Our explanation, of course, is not complete until we have explained—as we will do later—how the atomic polarization comes about.

18.5 Capacitors and Dielectrics

Consider again the X-ray tube discussed in the previous sample problem. How can a uniform electric field be produced? A single positive charge produces an electric field that points away from it, as in Figure 18.17.This field is not uniform, because the space between the lines increases as you move away from the charge.

CHAPTER 5 CAPACITORS

We have a capacitor whose plates are each of area A, separation d, and the medium between the plates has permittivity . It is connected to a battery of EMF V, so the potential difference across the plates is V. The electric field between the plates is E = V/d, and therefore D = V/d.
