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.

How do you calculate the cable size for a run of 30 meters?
to calculate the cable size of a run of 30 meters long you first will have to know the current of the appliance use the voltage drop formula V d = (mVxIxL)/1000 once the voltage drop is less than 2.5% of the nominal voltage, the cable should be upsize.
What causes low voltage to the transmission selonoid?
Cables aren't perfect conductors, they have a bit of resistance. This resistance cacuse a certain voltage drop. But the drop isn't proportional to the voltage running through the cable, so at lower voltages the proportion lost to internal resistance in the cable will be bigger than at higher voltages.
What gage wire for 240 volt 50 amp 100 feet?
It depends on the voltage being used. That is because the size of the cable is determined by its resistance, and to calculate the allowable resistance you need to know the voltage drop. Lower resistance means a thicker cable. Normally the allowable voltage drop is a percentage of the supply voltage, 5% for example. On a 120 v system this would allow a 6 v drop while on a 240 v system the voltage drop could be 12 v. So for a given load current, the cable for a 120 v system would need half the resistance and double the cross-section area than a cable for 240 v. But for a given amount of power, the current on the 240 v system would be halved, so the cable resistance could be four times higher and its cross-section one quarter of that needed for 120 v. That is why higher voltages are used to transmit power over long distances.
What size copper wire do you need for 339 amps running 150 feet?
It would depend on the voltage, because at a higher voltage a larger voltage drop can be tolerated for the same percentage voltage drop. That means a thinner wire could then be used. And 339 amps is a VERY high current for 120/240 volt system- more than double the peak demand for most houses. Please check your question, and give us the voltage used.
What does voltage equal?
V=IR To calculate your voltage drop (V), you multiply your resistance (R, measured in Ohms) and current (I, measured in Amps [A]) by each other the. The number you are left with should be your voltage drop.

What is the difference between voltage forward voltage and voltage drop?
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.
Where would you use xlpe cable?
for high voltage more than 11 KV and low current we can use XLPE cable.
If a cable must carry a current of 19.5A with a voltage drop of no more than 6V its resistance must not exceed?
r=v/i=6/19.5=0.3076923077ohm, so,the resistance value must not exceed 0.4 ohm.
Is forward voltage drop of schottky diode more than tunnel diode?
Yes, the forward voltage drop of a Schottky diode is usually more than the forward voltage drop of a tunnel diode. A Schottky diode voltage drop is between approximately 0.15 to 0.45 volt. The interesting thing that makes a tunnel diode different from other diodes is its "negative resistance region" with a "peak current" around 0.06 volt and a "valley current" around 0.30 volt.
If a cable must carry a current of 19.5a with a voltage drop of not more than 6v its resistance must not exceed?
U= RI U/I=R U/R=I You want the middle one 6/19.5=0.31 Ohms
What do you mean by DC forward voltage?
DC forward voltage is generally related to diodes. It means the voltage across the diode when the diode is forward biased, i.e. when the anode is more positive than the cathode. The forward voltage is the drop across the diode. The amount of drop is a function of current. For typical silicon diodes, the forward voltage drop ranges from 0.6 volts for very small currents, to 1.5 or more volts for large currents.
What is a pratctical application of voltage drop?
I am an electrician at an aggregate company. We run 600V 3phase motors on our conveyor belts. When each conveyor feeds on to the next, the furthest conveyors often see voltage drop at the motor. We can usually fix the issue by upgrading the size of the cable to a larger than necessary guage.
What will be the voltage drop across two core cable whose length is 1500m and voltage is 24v DC and load is 2 watts?
Unanswerable. You need to specify the core size and material. Using two 10 AWG wires with a diameter of 2.6 mm each, the voltage drop over 1500 metres would be less than 1 volt.
How can we check the starter's external wiring circuit for volt drop?
For voltage drop checking on the wire from the battery positive post to the starter main terminal, you place the voltmeter reading on the 1 to 3 volt range, (or what lower range you have). You then place one voltmeter lead on the positive battery post, the other lead you place on the starter positive terminal and have someone crank the engine. While the engine is cranking, you observe the voltage drop. It should be less than a volt. This seems strange because you would think the cable would not drop voltage but it sure can. If the battery post is dirty or bad connection, you could see a voltage drop all the way to the maximum 12 volts battery voltage depending upon the connection. Also you can check the return path the same way--- Negative case of the starter to the negative post on the battery for voltage drop. If it is more than a volt or two, you have a bad ground return circuit.
At high temperature the forward voltage drop across a diode can be expected to be more or less than it is at low temperature?
