Generally, the longer the wire, the more electricity will be lost because of resistance.

Thin wires have a what resistance to electron flow than do thicker wires?
Thin wires have a greater resistance rhan thick wires. Imagine a straw. The thinner the straw. the less liquid can get through. Wires work the same way.
Can you mistakenly hook up the wires on a starter solenoid backwards?
Yes Some have 6 or seven wires going to between one and four connection's.
How do you tell the difference in the negative and positive on a coil?
Normally the terminals are marked on the coil ( if it's a bosch coil the one marked 15 is the primary winding positive terminal ). The large center one is the secondary positive ( the one that leads to your distributor ) and the two on the sides of it are the positive primary and the ground. If you don't know wich one is wich disconect the battery then disconnect the two smaller wires and remember wich one goes where. Use an ohm meter to test the resistance between a good ground on the body or engine block on each wire. The one that has no or very low resistance is the ground wire. If you are holding a coil in your hand and it isn't marked use the ohm meter to check the resistance between the secondary positive and the other two terminals. There should be infinite resistance ( open circuit ) to the positive of the secondary and 6Kohms or there abouts to the common ground terminal.
What does a transformer between utility wires and your house do?
The transformer steps down the voltage from 600kilo volts which is what is at the power pole/lines to multiple strands of 120v or hot wires which is what your house runs off of.
1995 silverado starter wire sparks and clicks while starting?
I would unhook the BATTERY and then Check the starter wires, Clean and tighten the wires on the starter and make sure there not touching anything that would make them short out / spark. That should fix your problem.
What units descride in conduction between wires?
Ohms (of resistance).
Why resistance is high during short circuiting?
Resistance of a short circuit is actually very low, ideally it is 0 Ohms. In practice the resistance of a short circuit will be equal to whatever the resistance of the short circuited wires is, which is typically very small. So if you substitute very small resistance value R into Ohm's Law(I = V/R), you will get a very high current flowing. Where V=voltage,I=current.
Compared to thin wires electrical resistance in thick wires are?
The electrical resistance in thick wires is less than thin.
Why don't AC input wires to a transformer just short circuit?
The resistance of the winding in the primary of a transformer constitutes a load. As long as there is resistance then there is no short circuit. A short circuit is considered no resistance which develops an instantaneous high current. That is why fuses and breakers are inserted into the circuit to open the high current flow under a short circuit condition.
What two wires touching causes a short circuit?
the red wire and the blue wire A touching of two wires coming from any potential power source will cause a short circuit Short circuit relates to the quickest path back to the source with out any resistance to the current flow.
What are the approximations of open circuit and short circuit tests?
Firstly turn of the power before this test...Using a resistance or continuity tester you should get the following results:Short circuit: Very low resistance (nearly 0 ohms) or the bell will ring.Open circuit: Very high resistance (Somewhere in the range of Mega ohms) or the bell will not ring.The reason for this is because and open circuit has a gap in it (which has high resistance).The short circuit has wires that are crossed and so has a really low resistance.
If current equals voltage divided by resistance wouldn't current at 0 resistance or short circuit be infinity?
Theoretically yes. However, there is always resistance through joints,components and trace impurities in wires. A dead short is only a dead short for an instant at a fixed temperature. As heat rises so does resistance. Consequently current falls. also, resistance of zero would violate the laws of thermodynamics, because it would imply zero entropy

Why is the secondary of a transformer a short circuit?
If you are saying that the secondary (output) winding on a transformer seems to be a short circuit, it is very likely to be low resistance and may only be a few ohms if you measure the resistance with an ohmeter. The only way it would actually be a short circuit is if something has been inserted which has shorted the wires or it has overheated and burnt through. In which case there should be an acrid smell. Or if you can see the wires you would see they were burnt. A short in the circuit it is powering could cause the transformer to overheat, burn out and short.
How short circuits occurs?
A short circuit usually occurs when the insulation between wires breaks down and they become accidentally connected together.
Why do wires turn hot in a circut?
The current passing through them - since all wires have resistance.
Why should the connecting wires in a bulb be of low resistance?
This is to avoid energy losses in the connecting wires.
