Write down an expression for the energy stored in the magnetic field of an inductor when the current is i. Use this expression to derive an equation for the magnetic energy density of a solenoid. A resistor, inductor and capacitor all store energy through different mechanisms. Briefly describe the way that each of these components stores energy
In this experiment, you will determine and compare the quantity of heat energy released in three exothermic chemical reactions through application of Hess’s law. Reaction 1: NaOH(s) → Na+(aq) + OH-(aq) + x1 kJ Reaction 2: NaOH(s) + HCl(aq) → H2O(l) + Na+(aq) + OH-(aq) + x2 kJ Reaction 3: NaOH(aq) + HCl(aq) → H2O(l) + Na+(aq) + OH-(aq) + x3 kJ In order to accurately measure the heat released in each reaction, we will be using a calorimeter. As...
Experiment 7 - The Resistor Capacitor Circuit Learning Objectives: Understand the short and long time behavior of circuits containing capacitors. Understand the and the mathematical relationshin between the current through the circuit as a function time, resistance, capacitance, and potential difference 1. Understanding the models for the behavior of a capacitor in a circuit A capacitor is a device that stores energy in a circuit as potential energy in an electric field. In the simple circuit drawn on the night,...
Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
summarizr the followung info and write them in your own words and break them into different key points. 6.5 Metering Chamber: 6.5.1 The minimum size of the metering box is governed by the metering area required to obtain a representative test area for the specimen (see 7.2) and for maintenance of reasonable test accuracy. For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...
