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 has the lowest resistance copper wire or iron wire?

Why does more current flow through the bulb when the reed switch was replaced with copper wire?
Copper wire has apparently lower resistance than the reed switch. The lower electric resistance, the higher electric current.
Why is copper commonly use to make electric wires?
Copper is used to make electrical wire because it is ductile and is very conductive. The ease with which copper can be worked and drawn ("pulled" or "stretched") into wire (because of its ductility) makes it a great mechanical choice for wire. And copper is highly conductive, that is, it has a low resistance to electric current flow. These two properties make copper an excellent choice to make electrical wire.
Does copper wire conduct sound?
Since sound is the effect of vibrations in a media, copper can definitely conduct sound. However, as a wire it would have a certain damping factor, much a like spring, that would absorb the energy of sound vibrations. So a sheet of copper would conduct sound, but a thin wire would not.
Is copper wire a pure substance?
No. Copper used in wiring would not qualify as laboratory-grade (pure). It would be far too expensive to manufacture and would not improve the conductivity enough to make a difference. Some copper wire is even plated. Laboratory-grade (pure) copper is a single substance, the element copper.
Would not reduce resistance in a copper wire?
Resistance will only be reduced by changing the thickness of the wire or the wire's temperature. It's apparent impedance can be changed by placing it in an electric field as well.
How is copper losses reduced in transformers?
how to reduce copper losses in a transformer Copper losses are due to the resistance of the copper (or aluminum) windings. To reduce copper losses the transformer would have to be rewound with heavier gage wire.
Which material has a greater resistance aluminum or copper wire?
Aluminium wire has high resistance than Copper.
The properties of a wire that would create the least resistance to electron flow?
Generally a larger diameter copper wire would create the least resistance to electron flow. Copper is the most conductive and is widely used.
What has the lowest resistance copper wire or iron wire?

Can copper and alluminium wire of same length and diameter have same resistance?
For a single temperature, yes. The copper wire will have a much smaller cross-section than the iron wire. For multiple temperatures, no. Copper and iron have different temperature coefficients for resistivity.
Which wire would have the lowest resistance a long thin iron wire at a high temperature or a short thick copper wire at a low temperature?
Copper will.
Why copper strips are used in meter bridge wire?
The resistivity of copper is very low and as the strip is so thick then resistance would be almost zero.
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 has more resistance a nichrome wire or a copper wire?
Nichrome wire has such high resistance that it is used to convert electrical energy into heat. Many heating elements are made from nichrome. Copper wire has the best conductivity, for the price, of any metal.
Why is a copper wire not used to make filaments of electricbulbs?
Copper wire has low resistance, so it is unable to produce enough heat to glow.
A piece of copper wire was cut into n equal parts these parts are connected in parallel how will the resistance of the parallel combination compare with the resistance of the wire?
The resulting resistance of the parallel combination will be the resistance of the original wire divided by n squared.
