Chapter 6: Inductance and Capacitance
Chapter 6: Inductance and Capacitance We introduce here the two remaining basic circuit elements: the inductor and the capacitor. The behavior of the inductor is based on the properties of the magnetic field generated in a coil of wire. In fact, the inductor is basically a coil of wire. Ampere’s Law: current in a coil magnetic field

Experimental Verification of Kirchhoff’s Voltage Law and ...
courses.egr.uh.eduThe second of two resistive circuits constructed for this work. The circuit contains larger resistors than those of Figure 2 (taken from Reference 3). Kirchhoff’s Voltage Law and Kirchhoff’s Current Law were tested on the circuits shown in Figures 2 and 3. The test of KVL was performed by measuring voltage drops along closed paths
Response of First Order RL and RC Circuits
courses.egr.uh.eduFrom the current-voltage relationship for an inductor, we know that the at constant current, inductor acts like a short. Thus, the resistors R and R S have no current flowing through them, so the only current flowing is through the inductor, and i L = i S. Now we look at the situation for t > t 0. The switch has been

Introduction to Microstrip Antennas
courses.egr.uh.eduOverview of Microstrip Antennas. Also called “patch antennas” One of the most useful antennas at microwave frequencies (f > 1 GHz). It usually consists of a metal “patch” on top of a grounded dielectric substrate. The patch may be in a variety of shapes, but rectangular and circular are the most common. 8.
