You would have a misfire and it may damage the coil if operated long enough in that condition.
none the resistance is in the wire not the timer
A thin and long wire made of a material with high resistivity, such as nichrome or tungsten, would have the greatest electrical resistance.
Self resistance is exactly what it sounds like it would be. It is the resistance that you make happen on your own.
Superconductor wire would have the least resistance. Superconductors have zero electrical resistance when cooled to very low temperatures, allowing for an efficient flow of electrical current without any loss of energy.
The ignition coil would only affect the spark to the spark plug(s).
current will increase
Metals are conductive, but are not perfect conductors and so they have some electrical resistance. How the resistance of the metal is affected by "thickness" depends on what you mean by thickness. If the electrical current has to flow through a longer piece of metal, then the resistance of the metal to electrical flow would be greater. However, if you take that same length of metal and increase the area of the metal by increasing its "thickness", then the resistance of the metal becomes less.
The filament in an incandescent light bulb resists the flow of electricity. Copper wire has relatively low electrical resistance, making it a common choice for transmitting electricity. Insulators, such as rubber or plastic, have high electrical resistance, which prevents the flow of electricity.
corroded/dirty connections
Back up generators
a circuit with no resistance or zero resistance can be considered as open circuit in which the current is zero. without resistance the circuit just becomes open ()
I have never come across a symbol for an electrical resistance box. As the resistance box is a test instrument and it would not be drawn on any electrical schematic there may not be a symbol designated for it. The last letter of the Greek alphabet is (Ω omega) and it is used for the electrical symbol for resistance.
