Upon completion of this lesson, you will be able to calculate values

in DC series circuits.

This lesson replaces SA 0703.

Calculate resistance, current, voltage, and power in DC

series circuits.

Given the information provided in this lesson.

To demonstrate competency of this task, you must achieve

a minimum of 70 percent on the subcourse examination.

In any type of work that uses the effects of electron flow, a

knowledge of series or parallel circuits is desirable. None of the

effects which accompany electron flow--for example, heating,

lighting, or magnetic effects--are possible without the use of

electric circuits, and many electric devices can be more effectively

used if the operator has a knowledge of how the basic circuits work.

An electric circuit is a complete path through which electrons flow

from the negative terminal of the voltage source, through the

connecting wires, through the load, and back to the positive terminal

of the voltage source. A circuit is thus made up of a voltage

source, the necessary connecting wires, and the load.

A series circuit is defined as two or more component parts connected

end to end to form only one path for current flow.
