Direct Current Circuit
Teruo Matsushita · Electricity · 2023
In this chapter, we treat direct current circuits composed of resistors and direct current power sources (voltage source and/or current source), and determine the current and combined resistance. Intuitive and analytic solution methods are described and compared for deeper understanding. The Wheatstone bridge, which is a fundamental bridge circuit to measure unknown resistance, is introduced. We also learn the condition of matching, under which the maximum output power can be obtained from an electric power source with internal resistance.
