What is one thing that you could do to the wire used in a circuit to decrease the amount of resistance bulb by the wire?
Use thicker wire. Doubling the diameter gives one quarter the resistance.
Why you dont use simple wire instead of zero resistance?
A: if you have many people will more then glad to use it.
Does the type of wire make a difference to the circuit?
yes. If you use wire of certain resistance first the get the result and if u use other wire which is of more or less resistance then the voltage drop in the wire changes so the output also changes. Yes it does, but the difference may be inconsequential. The specific circuit in question and type of wire should be included for a specific answer.
How would you wind a coil which has a resistance but essentially no inductance?
I wouldn't. I doubt this is possible. Wire, by definition will have inductance. The inductance will increase as the frequency increases, so I guess you could specify a frequency that is extremely low to use the coil at.
Automobile batteries use low or high internal resistance?
I think you are asking why is it necessary for an automobile battery to have low internal resistance. That is because the internal resistance of a battery limits the amount of current it will produce. Imagine connecting a wire from the plus side of the batter to the minus side. Then, the amount of current the battery produces is the voltage of the battery divided by its internal resistance. So, if you take a flashlight battery and connect a wire between the two terminals, it might get a little warm. If you take a car battery cannot a wire between the two terminals, the wire will probably melt! (Don't try this!) If you take a lithium ion battery from your computer and short the two terminals, the battery will catch on fire. (Computer companies build extra resistance into the batteries to help to prevent that. So, why do cars need low internal resistance batteries? They need lots of current to start those large gasoline engines turning. You car battery does a tremendous amount of work to start your engine (and remember, energy and work are the same in physics).
Why the thin wire has grater resistance to electricity?
it has to do with ohms and the gauge of the wire. if you have a low ohms then you can't use a small thin wire. because the more ohms the more resistance. if you have a low omhs on a thin wire it can cause the wire to heat up. posibly catch fire.
What would reduce resistance in a copper wire?
Reduce the resistance:-- Use a shorter piece of wire.-- Use thicker wire.-- Cool the wire.Increase the resistance:-- Use a longer piece of wire.-- Use thinner wire.-- File a nick in the piece of wire you have.-- Stretch the wire.-- Heat the wire.
What is one thing that you could do to the wire used in a circuit to decrease the amount of resistance bulb by the wire?
Use thicker wire. Doubling the diameter gives one quarter the resistance.
Can you use a copper wire to make a filament of an electric bulb?
No, copper wire cannot be used to make the filament of an electric bulb as copper wire has very low resistance. Therefore, the bulb will not glow if current is passed. It would also melt - the filament has to be white-hot to be any use!
How can you measure resistance by using resistance thermometer?
You use an ohmeter. It sends current through the wire to determine value.
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.
Best material for making resistance wire?
Many people use steel and stainless steel, perhaps stainless steel welding wire to make cheap resistance heating elements.
Why you dont use simple wire instead of zero resistance?
A: if you have many people will more then glad to use it.

What multimeter modes could you use to determine if a wire is whole or broken?
Resistance and Continuity
Why does a heating element get hot when current flows?
The current is doing work against the resistance of the material which makes up the heating element.Because it has resistance.-- Whenever electric current flows through a resistance, it loses energyequal to (current-squared) x (resistance).-- When we connect components in an electrical circuit, we use wire withthe least possible resistance, so as not to lose energy in the wiring.-- When we want to warm up the lab, we use wire with significant resistance,in order to have it dissipate significant energy and radiate heat.
Can you use power wire for speaker wire?
Answer:It sure will. Why don't you give it a try? (Assuming here you aren't plugging this in the wall!)Answer:Absolutely. Just bear in mind that speakers are low-impedance loads, so the resistance of the wire must be considered. To minimize losses in the wire, you want to use a pair of wires that will have a resistance that is 5% or less than the impedance of the speaker. So, if you have a 4 ohm speaker and you want to run a copper pair 20 feet from the amplifier to the speaker, you need to use #16 (AWG) wire, as a minimum.See the link below for more than you will ever need to know about speaker wires.
