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.
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.
The unit of electrical resistance is the Ohm. It's written as the Greek capital Omega:Ω1 ohm = 1 amp per volt
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).
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
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.
The frequency formula used to calculate the resonance frequency of a tuning fork is f (1/2) (Tension / (Mass per unit length Length)), where f is the resonance frequency, Tension is the tension in the tuning fork, Mass per unit length is the mass per unit length of the tuning fork, and Length is the length of the tuning fork.
the electrical resistance of a conductor through unit cross-sectional area per length is called "resistivity of material"
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
The resistance of a wire increases as its length increases. This is because as the length of the wire increases, there are more atoms for the electrons to collide with as they pass through the wire, leading to more opposition to the flow of electric current and a higher resistance.
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.
The unit of temperature coefficient of resistance is ohm per ohm per degree Celsius or say resistance per resistance per degree Celsius.
The linear mass density formula is mass per unit length, denoted by (lambda) and calculated as mass divided by length. It is used to find the mass of a one-dimensional object by dividing its total mass by its length.
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.
Cross sectional area (square metres) * 7850 = kilograms per metre length.
The formula to calculate taper in millimeters would be: (small diameter - large diameter) / taper length. The result will give you the taper in millimeters per unit length.
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]
