BASIC ELECTRONICS - OD1633 - LESSON 1/PE 1
LESSON 1.
PRACTICAL EXERCISE - ANSWERS
Requirement
a.
A conductor is defined as any material that will permit the flow of
electricity through it, while an insulator is defined as any material
that blocks the flow of electricity through the material.
b.
The two types of agents used to extinguish a fire are carbon dioxide
(CO2) and potassium chloride or purple K (PKP).
c.
Ampere is defined as the basic unit of electrical current. Voltage is
the term used to signify electrical pressure.
Voltage is a force
which causes current to flow through an electrical conductor.
Resistance is defined as the opposition which a device or material
offers to the flow of current.
d.
The term efficiency of an electrical device is the ratio of power
converted to useful energy divided by the power consumed by the
device.
e.
A series circuit is defined as a circuit that contains only one path
for current flow.
f.
A circuit is said to be an open circuit when a break exists in a
complete conducting pathway.
g.
A short circuit is an accidental path of low resistance which passes
an abnormally high amount of current.
h.
A parallel circuit is defined as a circuit having
more
than
one
current path connected to a common voltage source.
