What should Iinclude in my science coursework? (Resistance of Wire) (Copper wire)?

Question

thanks

Answer 1

First of all the voltage drop across a resistor equal to its resistance times the current
So here is the famous

V=IR

Also Resistance R is defined as

R=Lp/A
where
L is the length of the conductor, measured in meters
A is the cross-sectional area, measured in square meters
p is the electrical resistivity (also called specific electrical resistance) of the material, measured in ohm • meter. Resistivity is a measure of the material's ability to oppose the flow of electric current.


Resistance of a wire is also temperature dependent
R= R0(1+aT)
R0 – resistance at T=0
a- Linear coefficient of resistace
T - temperature

I think you are dangerous enough to nail that poppy!
Good luck

Answer 2

You don't say anything more than your coursework so I do not know if you are poerforming a lab experiment or simply writing a paper or paragraph on the resistance of copper wire.
You might wish to note how resistance changes with temperature, especially try cooling the wire to freezing and measure the difference in resistance.
Use Boltzman's constant to calculate the effects on the copper wire.
Explain why good quality copper windings are used for magnetic coils and inductors and ferrite bead type inductors.
