Aabsolutely the resistance on any given wire is a combination of mainly two factors. The first factor is the material your conductor is made of and while almost anything conducts some level of electricity, metals are by far the best conductors with copper being the winner as far as corrosion, conductivity, ease of use, and, of course, cost effectiveness are concerned. So we know the first factor in the resistance on any given electrical circuit is the material it is made out of the second main factor is the length of that material. The resistance adds up the longer the run is. So the longer your piece of wire is the greater your resistance is. Now the wraps do not in of themselves add to the resistance of the circuit, but by adding more wraps you are adding length to your conductor thereby increasing its resistance.

Is there a direct correlation between increase in coil wraps and electrical resistance of a guitar pickup?
There is a direct relationship between the length of wire (thus the number of times the wire is wrapped) and the electrical resistance of the guitar pickup, measured at the two output terminals.
What is a positive negative correlation?
Correlation determines relationship between two variables. For example changes in one variable influence another variable, we can say that there is a correlation between the two variables. For example, we can say that there exists a correlation between the number of hours spent on reading and preparation and the scores obtained in the examination. One can infer that higher the amount of time spent on preparation may result in better performance in examination leading to higher scores. Hence the above is a case of positive correlation. If an increase in independent variable leads to an increase in dependent variable, it is a case of positive correlation. On the other hand if an increase in independent variable leads to a reduction in dependent variable, it is a case of negative correlation. An example for negative correlation could be the relationship between the age advancement and resistance to diseases. As age advances, resistance to disease reduces.
What does it mean when two variables have a positive correlation?
A positive correlation between two variables means that there is a direct correlation between the variables. As one variable increases, the other variable will also increase.
Difference between positive and negative correlation?
If the two variables increase together and decrease together AND in a linear fashion, the correlation is positive. If one increases when the other decreases, again, in a linear fashion, the correlation is negative.
What does a positive correlation between variables x and y imply?
It implies that an increase in x is accompanied by an increase in y. And similarly, they decrease together.
What does a correlation coefficient represent?
The correlation coefficient for two variables is a measure of the degree to which the variables change together. The correlation coefficient ranges between -1 and +1. At +1, the two variables are in perfect agreement in the sense that any increase in one is matched by an increase in the other. An increase of twice as much in the first is accompanied by double the increase in the second. A correlation coefficient of -1 indicates that the two variables are in perfect opposition. The changes in the two variables are similar to when the correlation coefficient is +1, but this time an increase in one variable is accompanied by a decrease in the other. A correlation coefficient near 0 indicates that the two variables do not move in harmony. An increase in one is as likely to be accompanied by an increase in the other variable as a decrease. It is very very important to remember that a correlation coefficient does not indicate causality.
When was the resistance thermometer invented?
The application of the tendency of electrical conductors to increase their electrical resistance with rising temperature was first described by Sir William Siemens at the Bakerian Lecture of 1871 before the Royal Society of Great Britain. The necessary methods of construction were established by Callendar, Griffiths, Holborn and Wein between 1885 and 1900.
What kind of relationship exists between the variables if your r value is close to plus 1?
When r is close to +1 the variables have a positive correlation between them; as the x-values increase, the corresponding y-values increase. There is also a strong linear correlation or relationship between the variables, when the value of r is close to +1.
Why hardness is important in metallurgy?
For steels especially, there is a high correlation between hardness and strength. Hardness is also indicative of wear resistance for a material.
What is the relationship between two quantites that increase or decrease together called?
If they increase or decrease exactly, then the constant of proportionality or coefficient of proportionality. If not exactly, then a correlation coefficient.
Is there any correlation between TDS and COD?
Not if TDS is consistent, there will be however a correlation if TDS fluctuates more than 10 per cent which tends to increase COD due to the degradation of microorganisms.
How does electrical resistance change the current in a circuit?
Electrical resistance is opposition to electric current flow. There is a resistance to the flow of current. And a "balance" between applied voltage and resistance determines how much current will flow in a circuit. For a given applied voltage, if we increase the resistance, the current flow will decrease. For that same applied voltage, if we decrease the resistance, the current flow will increase. It's a simple relationship, and it is set down by the following expression: E = I x R We can also write it as I = E / R and R = E / I Voltage (in volts) is E, current (in amps) is I, and resistance (in ohms) is R. In the first expression, voltage is equal to current times resistance. For a constant voltage, any increase in resistance will cause a decrease in current flow. And any decrease in resistance will cause in increase in current flow. Just as cited earlier.
