The direction of current is the direction positive charges flow, a definition adopted by Benjamin Franklin before it was determined that in most cases the charges that flow in a circuit are electrons (negative charges).
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.
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.
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
Electric Current: a flow of charged particles is an electric current. a more precise definition of current is the rate at which charge flows through a perpendicular surface of cross-sectional area A. in the last chapter we discussed the properties which determine how easily electrons to flow through a material.
Chapter 26: Direct current circuit •Resistors in circuits •Equivalent resistance •The nature of the electric potential and current in circuit •Kirchhoff’s rules (for complicated circuit analysis)
