What are 2 ways you could alter a wire to increase the resistance in an electric current?
#1). Thinner wire.Either replace a wire with one composed of thinner material, orstretch the existing wire slightly so that it becomes thinner.#2). Longer wire of the same thickness.
What is the relationship between resistance and temperature?
• ntc 'negative temperature coefficient': its resistance decreases as the temperature increases• ptc 'positive temperature coefficient': its resistance increases as the temperature increases
What is difference between ofc and copper wire?
The main difference is in the price. Oxygen-free copper is sold to people with plenty of money for loudspeaker wire, but provided the wire has less resistance than one tenth of the speaker resistance (usually 4 or 8 ohms), the resistance of the wire is immaterial, and ordinary copper wire is perfectly all right. Highly refined copper has about 1% better conductivity than the usual variety. That difference in conductivity is insignificant for audio use and is also produced by a 3 degree C temperature rise in copper.
From copper and manganin which has higher resistance?
The question is actually wrong, they can both have the same resistance if configured differently, the real question should be which has a higher resistivity which is the electrical resistance found in a standard amount of each material. In this case Manganin has a higher resistivity 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 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.
Does aluminum have lower resistance than copper?
No, aluminum has a higher resistance than copper.
Which material has a greater resistance aluminum or copper wire?
Aluminium wire has high resistance than Copper.
Cna you stretch copper into wire?
yes
What happen to the resistance of a copper when it is heated?
The resistance will go up.
Is copper low or high resistance?
Copper is low resiatance

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.
How do you determine length of copper?
As the question is some what blind: However if the cross sectional area of the copper wire/rod is uniform, then we can find the length is we know the electrical residence between two ends. That is the concept of specific resistance is entering into picture to calculate the resistance then the length.
Is it possible to do resistance welding on copper?
GUCCI
What is the relationship between resistance and temperature?
• ntc 'negative temperature coefficient': its resistance decreases as the temperature increases• ptc 'positive temperature coefficient': its resistance increases as the temperature increases
What is dynamic resistance and give you brief account about it?
A device's resistance to electricity, like in a wire's resistance to having electricity flowing through it, copper has very little, so that's why copper is used in wires.
