16 Αυγ 2023 · Consider a distribution of free charge dq of differential size within a macroscopic distribution of line, surface, or volume charge as shown in Figure 2-9. Then, the total charge q within each distribution is obtained by summing up all the differential elements.
13 Ιαν 2021 · Explain what a continuous source charge distribution is and how it is related to the concept of quantization of charge; Describe line charges, surface charges, and volume charges; Calculate the field of a continuous source charge distribution of either sign
The line charge density \(\rho_l\) at any point along the curve is defined as \[\rho_l \triangleq \lim_{\Delta l \to 0} \frac{\Delta q}{\Delta l} = \frac{dq}{dl} \nonumber \] which has units of C/m. We may then define \(\rho_l\) to be a function of position along the curve, parameterized by \(l\); e.g., \(\rho_l(l)\).
9 Ιουν 2018 · Electron microscope (EM) uses high-energy electron beam as probe instead of visible light. The electrons have shorter wavelength and provides very high-resolution capacity (0.1 nm) and 500,000 times magnification power. It is also easy to manipulate the electron beams.
