2024 BICSI ITSIMM - CHAPTERONE EXAM WITH CORRECT
ANSWERS
Metric System - CORRECT-ANSWERSBICSI tecnical manuals primarily follow
this measurement system known as the International System of Units.
Gauge change of 3 - CORRECT-ANSWERSApproximately:
*doubles / halves the conductor's cross-sectional area
*doubles / halves the conductor's resistance
*doubles / halves the conductor's diameter.
Copper - CORRECT-ANSWERSMost typical metallic transmission medium.
Less Resistance to the flow of Electrical Energy - CORRECT-ANSWERSThis is
why copper is preferred. It is also relatively economical when compared with
other metals.
Resistance - CORRECT-ANSWERSThe property of a conductor to resist the
flow of electricity through it. Resistance is expressed in ohms.
Ohms - CORRECT-ANSWERSHow resistance is expressed.
One Ampere - CORRECT-ANSWERSAllows one ohm of resistance to flow when
one volt of electrical pressure is applied.
V = I X R - CORRECT-ANSWERSOhms Law (One ohm of resistance will allow
one ampere of current to flow when one volt of electrical pressure is applied)
Can be restated. V is volts. I is current in amperes. R is resistant in ohms.
Page 60.
R = V / I - CORRECT-ANSWERSOhms Law. V is volts. I is current in amperes. R
is resistant in ohms.Page 60.
I = V / R - CORRECT-ANSWERSOhms Law. V is volts. I is current in amperes. R
is resistant in ohms. Page 60.
Higher Temperatures (in reference to conductor resistance) - CORRECT-
ANSWERSIncrease conductor resistance by approximately two percent for
each 5.5 degrees Celsius or 10 degrees Fahrenheit.
, Length of Cable (in reference to conductor resistance) - CORRECT-
ANSWERSResistance increases as the length of the cable increases. (e.g.
doubling the length of the cable doubles its resistance).
Unbalanced conductors (in reference to conductor resistance) - CORRECT-
ANSWERScontributes to undesirable distortion of the signal. The diameter of
the conductors of a pair is maintained at a close tolerance to keep any
resistance unbalance to a minimum.
Inductance - CORRECT-ANSWERSProperty of an electrical force field built
around a conductor that opposes any change in current flow in a circuit, both
ac and varying dB.
The field is steady (in reference to inductance) - CORRECT-ANSWERSdc is
flowing through the conductor.
The lines of force constantly build and collapse (in reference to inductance) -
CORRECT-ANSWERSac in flowing through the conductor
Energy loss (in reference to inductance) - CORRECT-ANSWERSThe opposition
varying current results particularly for high-frequency signals.
Inductive coupling - CORRECT-ANSWERSthe transfer of energy from one
circuit to another (power lines on a utility pole can inductively couple a
power surge onto telephone cables)
henry - CORRECT-ANSWERSThe basic unit of inductance
Capacitance - CORRECT-ANSWERSthe property of conductors that allows
storage of electric charges when potential differences (voltages) exist
between the conductors).
Two wire separated by insulation (in reference to capacitance) - CORRECT-
ANSWERSwill cause a voltage difference when separated by insulation. The
insulation (or dielectric / non-conductive material) separates the wires
resulting in a buildup (storage of electric charge) of capacitance between the
wire.
farads - CORRECT-ANSWERSwhat capacitance is measured in.
SI - CORRECT-ANSWERSThe international system of units is best known as
this.
SI 10-02 - CORRECT-ANSWERSThe standard for metric conversion practices
put together by ASTM and the IEEE.
