In general, circuits in which charge flows in one direction are direct current (DC) circuits. In alternating current (AC) circuits (such as those in your house) the current direction continually reverses direction. Despite this difference, many of the concepts addressed in this chapter apply to both DC and AC circuits. Batteries
DIRECT CURRENT. LEARNING OBJECTIVES. Upon completing this chapter, you will be able to: Identify the term schematic diagram and identify the components in a circuit from a simple schematic diagram. State the equation for Ohm’s law and describe the effects on current caused by changes in a circuit.
Direct-Current Circuits. 7.1 Introduction. Electrical circuits connect power supplies to loads such as resistors, motors, heaters, or lamps. The connection between the supply and the load is made by soldering with wires that are often called leads, or with many kinds of connectors and terminals.
The handbook includes information on alternating current (AC) and direct current (DC) theory, circuits, motors, and generators; AC power and reactive components; batteries; AC and DC voltage regulators; transformers; and electrical test instruments and measuring devices.
Lecture 9: Direct current circuits (ch.26) From ch.25 •how to do calculations involving energy and power in circuits. Looking forward at … •how to analyze circuits with multiple resistors in series or parallel. •rules that you can apply to any circuit with more than one loop. •Example problems (see the PDF files)
Basic Direct Current (DC) Theory – E03-001 1 DC SOURCES When most people think of DC, they usually think of batteries. In addition to batteries, however, there are other devices that produce DC which are frequently used in modern technology. 1.1 LIST the four ways to produce a DC voltage. 1.2 STATE the purpose of a rectifier.
Direct-Current Circuits. CHAPTER Direct-Current. 10 Circuits. ed to a cellular phone. This circuit’s components include resistors, capacitors, and diodes, all of which have been covered in previous chapters, as well as transistors, which are semi-conducting devices covered in C.
