When you talk of voltage, you should be thinking of the insulation factor of the wire. By the same token when you talk of wire size, it is based on the amperage the wire is required to handle.

Do conductors have low resistance?
Conductors have low resistance. Recall Ohm's law. The higher the conductor resistance, the greater the voltage drop along the conductor, and the less voltage that is available for the load. The conductor resistance is a resistance in series with the load. Also, higher conductor resistance results in more electrical power being converted into heat, warming up the conductors. This is calculated with the formula P=I2R. The greater the resistance, the greater the power wasted heating the conductors.
What is multiwire branch circuit?
A multiwire branch circuit is consist`of two or more ungrouded conductors that has voltage between them and has a grounded conductor that is eoual voltage between each conductor connect to the neutral and it,s ground
Is stacking of cables in cable tray permitted?
See NEC Article 392. It depends on the voltage, conductor size and the type of cable tray selected.
What material is the poorest conductor of electricity?
Rubber compound is one of the poorer conductors of electricity. That is why rubber tape is used in both high and low voltage splices.
You have 230v 3 phase power can you plug a 230v single phase motor into it?
Any two legs of a three phase system are classed as single phase. So yes a single phase motor will operate when connected. Be sure to use the proper motor protection devices to control the motor.
What is meant by minimum electrical clearance?
The minimum electrical clearance is the minimum distance between electrical conductors with different potentials (voltage). This generaly determined by the maximum possible voltage differenge between the conductors. Dimensions larger then the minimum electrical clearance are OK, however smaller dimensions start to risk arc-over between your conductors.

Why transposition tower in long transmission line?
In transmission line minimum 3 conductors are run in parallel. Every conductor has a flux which produce losses in other conductor which is run with parallel. So in the middle one conductor the losses is double in respect to other two conductors. At the end of the line the voltage of the middle one conductor is reduced from other conductors due to these losses. The transposition tower is used to change the conductors. By using these tower we shift each conductor position. So we use these towers in long transmission line so that these losses becomes equal for each conductor. and voltage will be almost equal at the end of the transmission line. Regards. Vishal kr.

How many voltage 3phase line?
For a three-phase, three-wire, system there are three conductors called 'line conductors', and there is a voltage between any pair of line conductors, so there are three voltages.For a three-phase, four-wire, system there are four conductors: three 'line conductors' and a 'neutral' conductor. So there are three line voltages (voltages between lines) and three phase voltages (voltages between any line conductor and a neutral conductor).
Can oil and alcohol conductors of electricity?
Everything is a conductor of electricity at a high enough voltage. Oil and alcohol aren't particularly good conductors, though.
What is multiwire branch circuit?
A multiwire branch circuit is consist`of two or more ungrouded conductors that has voltage between them and has a grounded conductor that is eoual voltage between each conductor connect to the neutral and it,s ground
Can you use phase voltage as a single phase?
A single phase supply can be obtained between any pair of line conductors or between a line conductor and a neutral conductor.
Do poor conductors produce more heat then the relatively good conductors?
Most of the metals are effective conductors of heat.They conduct heat without much loss in energy and quickly.Copper, silver are among best conductors of heat.metals are good conductor of heat.
The calculation used to determine amperage of a conductor based on the total number of conductors in a conduit is called A derating B voltage drop C conduit fill D conductor fill?
derating
Why resistance drop occurs in a conductor?
All conductors have some amount of resistance associated with them. There is voltage drop along the length of a conductor because the potential energy of the voltage is lost to heat losses (I^2 *R) due to this resistance. The more resistance, the more voltage drop. The current is set at a given voltage and power level.
What is the necessary condition for a conductor to obey ohm's law?
No. In fact, most conductors don't obey Ohm's Law.For Ohm's Law to apply, the ratio of voltage to current must remain constant for variations in voltage. For many conductors this simply doesn't happen and, for that reason, we call such conductors 'non-linear' or 'non-ohmic'.
Why high tension cables conductor are circular?
High-voltage conductors are circular to evenly-distribute the electric field that surrounds them in order to prevent breakdown.
