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.
Three factors that affect the resistance of a copper wire -?
There are three main factors that affect the resistance of a copper wire: Length of the wire: The resistance of a wire is directly proportional to its length. As the length of the wire increases, the resistance also increases. This is because the longer the wire, the more obstacles (collisions with electrons) the current has to overcome, resulting in higher resistance. Cross-sectional area of the wire: The resistance of a wire is inversely proportional to its cross-sectional area. As the cross-sectional area of the wire increases, the resistance decreases. This is because a larger cross-sectional area provides more space for the flow of electrons, reducing the resistance. Resistivity of the material: The resistance of a wire is also dependent on the resistivity of the material it is made of. Resistivity is an inherent property of the material and is a measure of how much the material opposes the flow of electric current. Copper has a relatively low resistivity compared to other metals, making it a good conductor and suitable for wiring applications. The relationship between these factors and the resistance of a copper wire can be expressed by the formula: R = ρ × (L / A) Where: R is the resistance of the wire ρ (rho) is the resistivity of the material (in this case, copper) L is the length of the wire A is the cross-sectional area of the wire By adjusting these three factors, you can control and manipulate the resistance of a copper wire to suit your specific needs in electrical and electronic applications.
A copper coil has a resistance of 100 at 20 degree Celsius What is its resistance at 50 degree Celsius if the temperature coefficient of copper is 3.93degree Celsius?
there isn't any go wipe ure bum your drippin
Does silver have a high or low resistance?
Silver is the best natural conductor. It has the lowest resistance of any known natural material. Your conductors - low resistance materials Silver, Copper, Gold, Aluminum, Tungsten, Brass, Iron, Platinum... Gold is sometimes favored in circuits as silver and copper both oxides.
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.
What would be the manipulated responding and controlled variables in this experiment?
The experiment consisted of copper pennies, 5 small beakers, and dropper bottles of: dish soap, water, ethanol, and baby oil. We had to drop these liquids onto pennies and see which could hold the most. So, what would be the manipulated, responding, and controlled variables in this experiment?
What are variables in an investigation?
The Independent/Manipulative variable is the variable that you purposely change, and the Dependent/Responsive variable is the variable that changes as a rest of the Independent variable. You measure the dependent variable to see the effects of the Independent variable.
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.
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.
Is it possible to do resistance welding on copper?
GUCCI
How do you do the experiment 'Which metal rust fastest copper bronze or steel?
i dont know of an experiment to test this but copper will not rust, and bronze being comprised of tin and copper, the answer to which will rust fastest is steel. I hope this helps you.
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.
What are the variables in a potato battery?
There are several variables involved in making a potato battery. Specifically, the variables include the potato, two pennies, galvanized nails, and some copper wire.
Why use copper powder not a piece of copper in an experiment?
To give a higher surface area for the reaction
