The development of electromagnetic theory was one of the great accomplishments of physics in the 1800s. Learning how to use electromagnetismElectromagnetism has given us the ability to make hundreds of different types of devices as well as provide electrical powerPower to every home and business. In the history of civilization, we are currently in the age of electricity. Some of the themes of the chapter are represented in Figs. 10.1, 10.2, 10.3 and 10.4. Figure 10.1 shows an electric power plant. Figure 10.2 shows a meter for measuring current and voltage in an electrical circuit. Figure 10.3 shows part of an electrical power deliverysystem. Figure 10.4 shows a bandpass filter.
