Resistance - Correct Answer Resistance is expressed in Ohms, and is the property of a conductor to resist the flow of electricity through it. V=IR Inductance - Correct Answer Is a property of an electromagnetic field built around a conductor that opposes any change in the current flow in a circuit Capacitance - Correct Answer is a property of conductors that allows storage of electric charges when potential differences exist between the conductors. Impedance (V) - Correct Answer Total opposition of current flow measured in Ohms American Wire Gauge (AWG) - Correct 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) - Correct Answer one million hertz, especially as a measure of the frequency of transmissions Megabit (Mb) - Correct Answer Approximately one million bits. Often used as a measurement of data transfer throughput. Bandwidth - Correct Answer The amount of data that can be transmitted over a network in a given amount of time. Decibel (dB) - Correct Answer A unit used to compare the loudness of different sounds. Crosstalk - Correct Answer when data bleeds from one pair to another in a cable
