It all depends on the quality of the cable and what is being sent through this cable. If we are talking audio signal, keep in mind that most audio is low powered. For example the microphone and it's transducer has a very low power, unless of course you are using Phantom Power in which case it will increase not only quality but also decrease the limitation of distance and degradation.
Yet with loudspeakers you can "get away" with some good distance (of course this is relative). I would not go more than 50' with a 18 gauge wire even if it is speakon with 4 connectors. Yet with 16 gauge or even 14 (if you can find it or you can make it) 100' is a pretty normal run.
Keep in mind the run and loss of signal is from the amplifier to the speakers, not the mixer. So to get around that issue you can use a good gauged snake to run from mixer to amp and put the amp on a stage and then connect the speakers to the amp.

∙ 9y agoIf you have a radius of 5um. we can calculate the resistance per unit length we will say its ("r") for the fluid inside the axon. An "AXON" is the long threadlike part of a nerve cell along which impulses are conducted from the cell body to other cells. Also looking at the conductivity ("gm") and the capacitance ("C") per unit length of axon for a myelinated axon of radius of ("10 Um").
- "Myelin is a dielectric (electrically insulating) material that forms a layer, the myelin sheath, usually around only the axon of a neuron. It is essential for the proper functioning of the nervous system. It is an outgrowth of a type of glial cell. The production of the myelin sheath is called myelination."
R=pI/A p=is the specific resistance. L= length of resistor A= cross section area. Capacitance ("C")= "E"A/d "E" is permitting. d=distance between plates of the capacitor. we will assume that p, d, and "E" are independent of axon radius.
r=6.37E9 n/m gm=3E-7 mho/m c=8E-10 F/m
r=R/l= p8/A8= r alpha 1/A alpha a/ (radius)^2
r 5um/10um= (10um)^2/(5um)^2=r 10 um =(r5um)*(25/100) r10/um= (6.37E9)/4 n/m= 1.59E9 n/m

Why should jockey not be pressed when it is moved in Carey foster's bridge?
When Jockey is pressed the length of conductor increases due to elasticity. Since resistance is proportional to length the resistance of the conductor also increases. So the voltage drop per unit length alters from its standard value. It causes error in our reading.
What unit is used to measure resistance?
The unit of electrical resistance is the Ohm. It's written as the Greek capital Omega:Ω1 ohm = 1 amp per volt
How do you compute energy loss in transmission line?
Energy loss is I^2*R losses. Calculate the transmission line resistance, and multiply by the current squared per unit time (seconds if in watt/seconds, for example).
What is residual resistivity?
The specific resisitivity - also called residual or inherent resistivity - of a particular material (scientifically called its specific resistivity) is measured in ohms per unit volume. It can be determined by measuring the resistance of a test conductor having unit length and unit cross sectional area or some other accurately-measured volume of the material.
Capacity of pipe?
In order to calculate the internal capacity of a pipe use the formula pi x internal radius x internal radius x length of pipe where pi = 3. 142. This is the volume of a cylinder; pipe capacity is usually amount of flow per unit of time under given conditions of internal roughness, and viscosity of the flowing fluid with a given pressure loss per length unit
How does the resistance of a wire vary with its lenght?
If the wire's cross-section area is constant, then its resistance per unit length is constant, and the total resistance should be directly proportional to the length of a wire segment.
Which has more resistance a thick or a thin wire?
For a given material, a wire of smaller cross-section will have higher resistance per unit length.
What is resistivity of material?
the electrical resistance of a conductor through unit cross-sectional area per length is called "resistivity of material"
What are the primary coefficient of transmission lines?
Primary and secondary coefficientsFor a metallic transmission line there are defined the primary coefficients:R - resistance in ohms per unit length;G - leakance in siemens per unit length;L - inductances in henries per unit length;C - capacitance in farads per unit length.The secondary coefficients are the characteristic impedance (Z0) and the propagation coefficient (g )BY: OLOKUN MAYOWA SAMUEL - 08039406605
How Conduct related to conduction?
Conductivity is the inverse of resistivity. (i.e. conductivity = 1/resistivity) Resistivity is the resistance per metre of material. So a material will have a resistance of its length multiplied by its resistivity. So the resistance of an object is calculated from conductivity of the material from which it is made and its length by resistance = 1 / (conductivity * length) This makes no attempt to account for capacitance or inductance, so the impedance of a material would be calculated from conductivity as well as capacitance (or inductance) per unit length.
What is the units of temperature coefficient of resistance?
The unit of temperature coefficient of resistance is ohm per ohm per degree Celsius or say resistance per resistance per degree Celsius.
Why should jockey not be pressed when it is moved in Carey foster's bridge?
When Jockey is pressed the length of conductor increases due to elasticity. Since resistance is proportional to length the resistance of the conductor also increases. So the voltage drop per unit length alters from its standard value. It causes error in our reading.
How can you calculate the unit weight of MS squre or ractangular pipe?
Cross sectional area (square metres) * 7850 = kilograms per metre length.
What is the dimension of gravitation?
Gravitation can be expressed as either an acceleration or a force per unit mass.[Acceleration] = [Length/Time2][Force per unit mass] = [mass-length/Time2] per [mass] = [length/time2]
What is the difference between yield stress and proof stress?
yield stress is the maximum resistance to deformation per unit area and proof stress is the allowable resistance to deformation per unit area.
What do you call the change in length per unit length per degree rise in temperature?
coefficient of expansion
How do you make centimeters in length into centimeters per second?
A centimetre is a unit of length. Centimetres per second is a unit of speed. The two units are therefore incompatible.
