What else can I help you with?
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.
How can I check the resistance in a wire?
To check the resistance in a wire, you can use a multimeter. Set the multimeter to the resistance (ohms) setting, then touch the probes to each end of the wire. The multimeter will display the resistance measurement in ohms.
What would reduce resistance in a copper wire?
Reducing the temperature of the wire will decrease its resistance. Also, using a wire with a larger cross-sectional area will lower resistance since there is more room for electrons to flow. Finally, using a more conductive material than copper, such as silver, can reduce resistance.
How can I check the continuity in a long wire?
To check continuity in a long wire, use a multimeter set to the continuity or resistance mode. Connect one probe to one end of the wire and the other probe to the opposite end. If the multimeter shows a low resistance reading or beeps, it indicates that there is continuity in the wire. If there is no reading or beep, there may be a break in 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.
How can you measure the resistance of a wire accurately?
To measure the resistance of a wire accurately, you can use a multimeter set to the resistance measurement mode. Connect the probes to each end of the wire and read the resistance value displayed on the multimeter. Make sure the wire is not connected to any power source and is at room temperature for accurate results.
What methods would you use to test the resistance of a long and short wire?
To test the resistance of a wire, you can use a multimeter set to the resistance measurement mode. For a long wire, connect the probes at each end of the wire to measure the resistance. For a short wire, connect the probes very close to each other to measure the resistance. Make sure the wire is not connected to any power source during the measurement.
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.
How can you measure resistance by using resistance thermometer?
You use an ohmeter. It sends current through the wire to determine value.

How to measure the resistance of a wire accurately?
To measure the resistance of a wire accurately, you can use a multimeter. Set the multimeter to the resistance measurement setting, then connect the probes to each end of the wire. The multimeter will display the resistance value in ohms. Make sure the wire is not connected to any power source and is not touching any other conductive material for an accurate measurement.
Why not use an ohm meter to measure the leakage in wire insulation?
An ohm meter measures resistance in a circuit, not leakage in wire insulation. To measure insulation resistance or leakage in wire insulation, you would typically use a megohmmeter or insulation resistance tester, which applies a higher voltage than an ohm meter to test the integrity of the insulation.
