●● NVP
Answer: Nominal Velocity of Propagation
●● Insertion loss
Answer: The difference in the amount of power received before and
after something is inserted into the circuit.
●● Resistance
Answer: Resistance is expressed in Ohms, and is the property of a
conductor to resist the flow of electricity through it. V=IR
●● Inductance
Answer: Is a property of an electromagnetic field built around a
conductor that opposes any change in the current flow in a circuit
,●● Capacitance
Answer: is a property of conductors that allows storage of electric
charges when potential differences exist between the conductors.
●● Impedance (V)
Answer: Total opposition of current flow measured in Ohms
●● American Wire Gauge (AWG)
Answer: A standard rating that indicates the diameter of a wire, such as
the conducting core of a coaxial cable or the twisted pairs in a UTP
cable.
●● Megahertz (MHz)
Answer: one million hertz, especially as a measure of the frequency of
transmissions
