The Hall coefficient has the same sign as the charge carrier. The charge carrier in a normal electric current, the electron, is negative, and as a result the Hall coefficient is negative.

The graph of a line goes down and to the right when?
the coefficient of x is negative
What is a negative value?
A value that is negative, e.g., -5.
What is the value of coefficient of restitution for the perfectly plastic body?
the coefficient of restitution for the perfectly plastic body is zero(0). the coefficient of restitution for the perfectly elastic body is one(1).
A solid homogenous sphere rolls without slipping down a plane that makes an angle of 30 degree with the horizontal find the linear acceleration of the sphere and the minimum coefficient of friction?
There is no minimum value for the coefficient of friction. And the linear acceleration will depend on its unknown value.
When the block of mass is increased is there an increase in the value of coefficient of kinetic friction?
No, coefficient of friction is dependent on the materials in contact, not their mass. However the FORCE of friction will increase as the mass increases in this case.
When the a value or the coefficient of the X-Squared term is negative then the quadratic has a minimum value at its vertex?
No.
What is significance of Hall coefficient?
physical significance of hall coefficient
Why intrinsic semiconductor has negative halls coefficient?
The difference in the electron and hole mobilities is responsible for the small negative Hall coefficient of intrisic semiconductors. Refs: C.M.Hurd : Hall effect in metals and alloys R.Asokamani :solid state physics Busch& Schade; Solid state Physics
Can a coefficient of a variable be negative?
Yes, a coefficient of a variable can be negative.
What is the effect of temperature on hall coefficient of a lightly doped semiconductor?
hall coefficient of a lightly doped semiconductor will decrease with increase in temp as hall coefficient is inversely proportional to number density of charge carriers.
What is the range of correlation coefficient and what does its value tell?
The product-moment correlation coefficient or PMCC should have a value between -1 and 1. A positive value shows a positive linear correlation, and a negative value shows a negative linear correlation. At zero, there is no linear correlation, and the correlation becomes stronger as the value moves further from 0.
What is the Value of Hall coefficient of germanium n type?
-(1.907±0.071)*10^-2 m^3/C
Is it possible for a coefficient of variation to be negative?
Of course it is! If the mean of a set of data is negative, then the coefficient of variation will be negative.
Is it possible for a coefficient of variation to be negative Explain.?
Of course it is! If the mean of a set of data is negative, then the coefficient of variation will be negative.
Does a safe reactor have a positive or negative 'temperature coefficient of reactivity'?
negative 'temperature coefficient of reactivity'
How change of origin or scale effect value of co-efficient of co-relation?
The correlation coefficient is unaffected by change of origin or scale unless one of the sets of variables is multiplied by a negative term, in which case the correlation coefficient will become negative.
What is the meaning of negative coefficient of x?
In the form y=mx+b, b is the y-intercept and m is the coefficient, so if an equation has a negative coefficient, m<0. As a graph, the slope of the line is negative.
