ELECTRONIC PRINCIPLES - OD1647 - LESSON 1/PE 1
l. The area of the plates.
The distance between the plates.
The dielectric constant of the material between the plates.
m. Direct current is an electrical current which flows in only
one direction.
Alternating current is an electrical current which is constantly
varying in amplitude, and which changes direction at regular
intervals.
n. The dc voltage must be generated at the level required by
the load.
o.
p.
(a) The field consists of concentric circles in a plane
perpendicular to the wire (b) the field of each turn of wire
links with the fields of adjacent turns producing a twopole
field similar in shape to that of a simple bar magnet.
q. Frequency is the number of complete cycles of alternating
voltage or current completed each second.
r. The period measures time and the wavelength measures
distance.
s. An electronic device which operates by virtue of the
movement of electrons within a solid piece of semiconductor
material.
t.
Electron flow and hole flow
u.
Grown, Fused Alloy, and PointContact
v.
The AN/USM281C oscilloscope is a lightweight, solidstate
instrument designed for the general purpose of waveform
measurements using single or dualtrace displays with
normal or delayed sweep.
w. The four units of the AN/USM281C oscilloscope are the main
frame, vertical amplifier, dual time base, and the cover.
