I was trying to visualize this in my head and it made no sense..... the simplest circuit imaginable, a 10 watt resistor connected between + - of a 5v regulated power supply, the resistor value let's say 5 ohms...
We now have 1 amp running through this circuit, now here's the question lol.. I Take a wire I snip off a meter's worth I strip the plastic off and I'm left with 20 - 30 individual strands of copper wire, I connect a single strand of copper wire between + of the regulator/battery whatever to the Resistor
[+] ~~~~ (1 strand of wire)~~~~~~--------- [5ohm Resistor]-----------------------------[ - ]
That single strand of wire will get hot enough to melt plastic. Add, 10 or so more strands of wire, and then run the circuit, the wire no longer gets hot, it stays cool and does not melt the plastic...
Why?
