A longer wire has a higher resistance, because there are more particles for the electrons going around to "hit", and therefore be slowed down from.

Does a short copper wire have more resistance then a long one?
No. Other things being equal, a long wire has more resistance than a short wire.
What is difference between semiconductor and superconductor?
A semiconductor only allows some electrons to flow across its junction. It has some resistance, in fact more resistance than a conductor but less than an insulator. A superconductor has no resistance.
Why is the resistance of a long wire greater than a short wire?
The electricity that we use is the flow of electrons jumping from atom to atom within the atomic/molecular structure of the conducting material. Metals, like copper, commenly used for wires, have a dense molecular structure consisting of atoms that easily receive and release extra electrons. It does, however, require energy for an electron to pass through the space in between the atoms, resulting in a loss of energy. This loss of energy is mesured in resistance. The longer the wire, the longer the chain of atoms an electron must jump between. Just like climbing a ladder, the longer the ladder, the more steps you must take to reach the end, and the more energy used.
Do short wavelengths have a higher velocity than long wavelengths?
No.
Why a hair dryer has a high- heat setting with a lower resistance than the low-heat setting?
Because a higher resistance would have resulted in more heat loss, but the higher is he current, the more energy is lost to heat. Therefore, a lower resistance would release more heat.AnswerPower is equal to voltage squared divided by resistance. So, for a given voltage, the lower the resistance the higherthe power.
Does a short copper wire have more resistance then a long one?
No. Other things being equal, a long wire has more resistance than a short wire.
Does long wire have a lower or higher resistance than short wire?
A long piece of wire will have more resistance in it than a shorter one of the same material.
Is a firm's demand for labor curve is more elastic in the short run than in the long run?
No. It's more elastic in the long run than the short run.
Will a short thick metal wire have better resistance compared to a long narrow metal wire?
"Better" depends on how much resistance you need for your circuit design.A short thick wire will have less resistance than a long thin wire of the same substance.Whether that's better or worse depends on how you plan to use the wire.
Is short hair more popular than long hair?
More girls have short hair than long hair but I personally think long hair is much more beautiful. It is harder to take care of long hair but it is worth it.
Is medium relationships more lasting than short relationships?
Yes it is more long lasting then a short relationship
Are short or long hairstyles the trend for women in 2011?
Long hairstyles are the trend. You can do alot more with long hair than you can with short. However, some people feel that it is more professional to have short hair.
Does long hair carry more static electricity than short hair?
yes
Why might the current in a short circuit be higher than the current in the original circuit?
The current in a short circuit may be very high because the resistance in the short circuit is probably less than the resistance in the original circuit.
Do long vowels have more vowels than short vowels?
long vowels and short vowels are both just vowels they can't have more or less of themselves
Long range forecast products tend to be more accurate than short range ones?
Long-range forecast products tend to be more accurate than short-range ones. False
What is long haul and short haul tour operators?
long haul is more than five hours and short haul is less than five hours from UK
