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

storage of electric charges when potential differences exist between the
conductors.
Impedance (V) - 🧠ANSWER ✔✔Total opposition of current flow measured
in Ohms
