∙ 14y agoWhen 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.

∙ 14y agoConductors 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.
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
See NEC Article 392. It depends on the voltage, conductor size and the type of cable tray selected.
Rubber compound is one of the poorer conductors of electricity. That is why rubber tape is used in both high and low voltage splices.
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.
To calculate the minimum conductor size, you need to consider the current carrying capacity of the conductor, the length of the run, and the voltage drop allowance. Use the appropriate electrical code or standard for guidance on sizing conductors based on these factors to ensure safety and optimal performance of the electrical system.

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.

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).
Minimum electrical clearance refers to the shortest distance permitted between two conductive parts, such as wires or electrical components, to avoid electrical breakdown or arcing. It is important to maintain this clearance to prevent short circuits, electrical faults, and potential safety hazards in electrical systems.

A single phase supply can be obtained between any pair of line conductors or between a line conductor and a neutral 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.

In science, a conductor is a material that allows the flow of electricity. Conductors have loosely bound electrons that are free to move when a voltage is applied, allowing the transfer of electrical energy. Metals like copper and aluminum are common examples of conductors.
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'.
Yes, poor conductors typically produce more heat than good conductors. This is because poor conductors have higher resistance to the flow of electricity, leading to more energy being converted into heat as the electricity passes through them. Good conductors, on the other hand, have low resistance and therefore generate less heat.
