Hi guys,(adsbygoogle = window.adsbygoogle || []).push({});

I am trying to calculate the power and temperature lost from a cable. So I can do some crude thermodynamic calculations on heat transfer.

I am assuming in this case that the object next to the cable is touching, and I am trying to calculate how much power and temperature is transferred from the cable to the neighbouring material.

I have presently been calculating it with the Power = VI and the temperature loss is equal to I^2 x R.

I am not that great at the electronics but I think I am actually calculating just the power in the cable and I am being stupid in assuming this is the actual power transmitted to the surroundings I would just like some clarrification or correction if I am misleading myself.

Thanks for any help in advance,

Finch
