What else can I help you with?
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.
What is the electrical resistance of a penny?
The electrical resistance of a penny can vary based on its composition and condition, but a typical copper penny (post-1982) has a resistance of about 1 to 2 ohms. This value can change due to factors like oxidation, surface condition, and temperature. Generally, the resistance is low due to copper's excellent conductivity.
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.
What copper wire would have the highest resistance?
A thicker copper wire will have higher resistance as it will offer more opposition to the flow of electrons compared to a thinner wire. Additionally, a longer copper wire will have higher resistance compared to a shorter wire due to increased distance for the electrons to travel. Finally, a copper wire with impurities or defects will have higher resistance than a pure copper wire.
What are the three factors that would give a piece of copper wire high resistance?
High resistance in a copper wire can be caused by factors like a longer wire length, a thinner wire diameter, and the material's high temperature, which increases resistance due to increased collisions among electrons.
What happen to the resistance of a copper when it is heated?
As copper is heated, its resistance increases. This is due to the increase in collisions between free electrons and copper ions, hindering the flow of electric current through the material.
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.
Will a thicker or thinner copper wire of the same length allow more electric current to pass through?
A thicker copper wire will allow more electric current to pass through because it has lower electrical resistance. Thinner wires have higher resistance due to increased resistance per unit length. This causes more voltage drop and heat dissipation in the wire, limiting the amount of current that can flow through.
Does aluminum have lower resistance than copper?
No, aluminum has a higher resistance than copper.
Why is thick copper wire good for carrying current?
Thick copper wire is good for carrying current because it has a lower electrical resistance compared to thinner wires. Lower resistance results in less energy loss through heat generation, making thick copper wire more efficient for transmitting large amounts of current without overheating.
Cna you stretch copper into wire?
yes
What happens to the resistance of copper wire as the temperature of the wire increases?
The resistance of copper wire increases as the temperature of the wire increases. This is due to the increase in collisions between free electrons and atoms in the wire, which hinders the flow of electricity.
What material has the lowest resistance plastic copper or wood?
Copper has the lowest resistance among plastic, copper, and wood materials. Copper is an excellent conductor of electricity compared to plastic and wood, which have higher resistance due to their insulating properties.
Why is thick copper wire good for carrying a current?
Oh, dude, thick copper wire is like the superhero of conducting electricity. It's all about that low resistance life - the thicker the wire, the less resistance it has, which means more current can flow through without getting all tangled up. So yeah, thick copper wire is like the VIP lane for electrons, just breezing through without breaking a sweat.
Which material has a greater resistance aluminum or copper wire?
Copper wire has greater resistance than aluminum wire. This is because copper is a better conductor of electricity than aluminum. This means that copper wire will have less resistance and will be able to carry more current with less energy loss.
