Starting Problems

Really? You should go back and read some of your other posts then.



This is crap. If the conenctions are not making good contact then what? You're saying that the current INCREASES through the wire? What do you think CAUSES a wire to heat? Running more current than the wire is able to handle.

If you're going to critique then use your head.

Hes saying that the RESISTANCE increases through a wire. it DOESN'T matter if you used a 0 gauge wire, if you made a bad connection then it would heat up. If a bad connection is present somewhere then resistance increases throughout the whole circuit. You guys are trippin on each other you need to be aware of simple electrical theory.

That is incorrect. If what you are saying is true then any circuit involving a resistor or transistor would cause the entire circuit to heat as opposed to just that component itself. If there is a bad connection incapable of supplying adequate current, then the portion of the that cicuit that heats would be the contact portion (the area around the root cause of the restriction). A light bulb filliment for instance, does not cause all of the wiring in your home to heat up to the temp of the filliment. Nor does installing a resistor in a circuit, cause the wires fore and aft of that resistor to heat up.

Edit: An example of a case where a wire would heat would be where there was a break in a wire. That would cause heating localized to the damaged portion of the wire and would dissipate the further away it got from the break. Where this relates to the orginial topic is that he stated that both wires were getting hot. That indicates a short somewhere in the circuit causing excessive amounts of current to be carried through both wires.

Most of what you're saying in your two posts is correct however, your application is in error. It's true that creating resistance in any portion of a circuit decreases the current in the rest of the circuit but the part that doesn't apply is suggesting that the rest of that circuit would also heat as a result of it.
