What is the limit of volts possible per amp? For whatever conductor, a superconductor let's say.
yungman said:Good example is the HV transmission lines, they use towel to keep it way above ground.
LURCH said:I agree there is no limit, based on the following reasoning;
A well-insulated ellectrode can have a potential (voltage). In this case, the ellectrode can be charged up to any arbitrary voltage with no current flow at all. So, ratio of voltage to current can be infinite.
Nile3 said:I think you meant tower.
Okay well, why not use only 1 amp and 10 megavolt instead of 100 amp + 100kvolts? I mean, there must be a point where adding potential difference just doesn't have anymore effect on increasing current transfer.
rcgldr said:In the real world, the voltage limit is when the voltage ionizes the air which then acts as a conductor. For a spherical conductor in air:
Voltmax = radius (meters) x 3 x 106 (Newtons / coulomb)
Nile3 said:Well I must not understand how electricity works properly then. I was certain that there ought to be a limit in voltage per amp for any conductor in a vaccum...
Nile3 said:Let's say you have planet A which is completely positive and planet B which is negatively charged. A multiple kilometer long line of pure diamond is attached between them. The line is only 5 mm in diameter. How many volt for each amps can the current be made of at the maximum?
Nile3 said:Just a last question, if the planets charge are very high, why would distance affect their voltage? I mean electricity cannot propagate through vaccum, so there's no difference if they are 1 km or 100 appart correct?
The limit of Volts possible is determined by the maximum potential difference that can be created between two points. This is known as the breakdown voltage and varies depending on the material and design of the system.
The limit of Volts possible is influenced by factors such as the distance between the two points, the type of material used, and the presence of any insulators or conductors in the system. Temperature and external electric fields can also play a role in determining the limit of Volts possible.
No, there is no universal limit of Volts possible. The breakdown voltage can vary greatly depending on the specific system and its components.
Yes, the limit of Volts possible can be exceeded in certain situations. This can occur when the system is under high stress, such as during a lightning strike, or when the breakdown voltage is not accurately predicted or accounted for in the design of the system.
Knowing the limit of Volts possible is important for ensuring the safety and functionality of electrical systems. Exceeding the limit can lead to equipment failure, damage, and even electrical hazards. By understanding the limit of Volts possible, scientists and engineers can design and operate systems within a safe and efficient range.
