Turn signal problem
2003 Gulfstream Class A (freightliner chassis). This morning when I checked my turn signals prior to hitting the road I encountered this problem: regardless of whether signaling a left or right turn,...

Well now, if thin filaments were actually less resistive as you say Mr OnaQuest, why would is be necessary to use thicker and much less resistive wires for battery jumper cables.
In the back of every electrical code book is a chart that gives you the resistance of wires over a distance. It states very clearly that a thin wire has a lot more resistance than a thick wire.
In a series circuit at 12 volts with three 2 ohm filaments, each will glow equally bright. In a series circuit with the same overall resistance of 6 ohms, but with two thin elements of 2.5 ohms each, and one thick element of only one ohm, the wattage of each element is determined by using current squared times resistance. Wattage in each element then is
thick filament, 2Amps times 2 amps times 1 ohm = 4 watts
thin filament 2 amps times 2 amps times 2.5 ohms = 10 watts
this is why the thin filaments glow brighter in the series circuit when power goes through the thick turn filament, then the two thin run filaments.
