series circuits.
CONDITION:
Given the information provided in this lesson.
STANDARD:
To demonstrate competency of this task, you must achieve
a minimum of 70 percent on the subcourse examination.
INTRODUCTION
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.
