There must be current flow through the circuit to measure any voltage
15 by 67 that will give you the actual amount
The question can't be answered without knowing what the voltage is. That is because the allowed voltage drop is 5% of the supply voltage, so you need to know the supply voltage. Then the wire calculation aims to find out what the minimum size of wire is that produces that voltage drop or less.
The voltage drop in a wire has nothing to do with the insulation. Voltage drop has to do with the cross sectional area of the wire.
Absolutely, you will have voltage drop, maybe enough voltage drop that the welder will not work <<>> To do a voltage drop calculation for the 200 foot cable the input amperage of the welder needs to be stated. At a maximum distance of 201 feet and limiting the voltage drop to 3% or less, a #6 copper conductor can deliver 37 amps on a 220 volt system. Check the nameplate on the welder to see if it falls withing the range of 37 amps input amperage. Do not use the welders output amperage.
A 2/0 copper conductor will limit the voltage drop to 3% or less when supplying 125 amps for 230 feet on a 240 volt system.
According to the NEC (national electric code) a maximum of 2% voltage drop is allowed.
For voltage drop calculation you must use the current of the load and the distance of the load from the supply source. The circuit breaker is then used to limit the current to the rating of the wire that feeds the load.

the voltage drop means whenever the conductor passing through the supply voltage, according to the resistivity property to reduces the some amount of voltage that drop is known as voltage drop for example the resistance is used to drop the voltage to the circuit.............................................
Voltage drop is caused by circuit resistance
The voltage drop in a line can be decreased by
Voltage drop is caused by resistance. From the equation V=IR the voltage across that resistance can be calculated. For a uniform conductor the resistance is linear with the length R=kx where k is in ohms per foot. For a given current, the voltage drop V=Ikx so the voltage drop per foot is Ik. Voltage drop per foot can be measured, allowing a calculation of voltage drop for very long lengths of conductor such as power transmission lines. This is a reasonable approximation as long as the total voltage drop in transmission is small relative to the supply voltage. If the voltage drop is large, the current will be limited by the total resistance. This implies that long distance transmission lines should be high voltage, because 1 megawatt at 10,000 volts requires 100 amps, while at 100,000 volts it only requires 10 amps. The voltage drop per foot for the same conductor would be 10 times as large at 10 times the current, and the power loss (I*IR) would be 100 times as large. For alternating current, inductance can be a factor; this implies that relatively low frequency would be preferred.
The effect of diode voltage drop as the output voltage is that the input voltage will not be totally transferred to the output because power loss in the diode . The output voltage will then be given by: vout=(vin)-(the diode voltage drop).
because the voltage likes to drop
This is a voltage drop question. To answer this question a voltage needs to be stated. This is a calculation for a 120/240 service. A 3/0 aluminum conductor will limit the voltage drop to 3% or less when supplying 50 amps for 500 feet on a 240 volt system.
The voltage drop in a wire has nothing to do with the insulation. Voltage drop has to do with the cross sectional area of the wire.
Voltage is the potential difference between the source & any point in the circuit. The forward voltage is the voltage drop across the diode if the voltage at the anode is more positive than the voltage at the cathode (if you connect + to the anode). Voltage drop means, amount of voltage by which voltage across load resistor is less then the source voltage.
It will decrease the voltage drop.
