How Can I Calculate Wire Temperature Consistently for Electrical Projects?

AI Thread Summary
To calculate wire temperature consistently for electrical projects, it is essential to consider both heat generation and heat dissipation. The discussion highlights the need for heat transfer calculations to estimate the steady-state temperature of the wire, rather than relying solely on increasing temperature assumptions. It is acknowledged that accurately estimating these temperatures can be complex, often requiring practical measurements rather than theoretical calculations. The consensus is that understanding the balance between heat input and cooling is crucial for maintaining desired temperature levels. Overall, a comprehensive approach that includes both heating and cooling factors is necessary for effective temperature management in wire applications.

I am looking to determine the temperature in a certain gauge wire, fed by a battery pack. I am looking to design the battery requirements and wire size in order to maintain a certain temperature. The electrical calculations (I am not an electrical engineer) I have found all assume continually increasing temperatures. Am I right in assuming that I would need to calculate the heat dissipation using heat transfer calcs in order to determine the relatively constant temperature that would be obtained based on my parameters? Or is there a straight forward calc that can be used to estimate (I do not need exact temps) the temps that would be maintained in the wire? All help is greatly appreciated.

If you continually put heat into something but it can't escape, the temperature will keep rising.

So, yes, you do need to consider the cooling as well as the heating.

Unfortunately, this is probably more difficult to estimate than to actually build it up and measure it.

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
