Applying a negative or positive sign to power factor is an obsolete method of describing whether it is 'leading' or 'lagging'. We no longer do this. These days, a 'leading power factor' indicates that the load is capacitive and the load current is leading the supply voltage, and a 'lagging power factor' indicates that the load is inductive, and the load current is lagging the supply voltage.
Having said that, a 'negative' power factor is also the mathematical consequence of 'negative power' -i.e. the direction of power when it is fed from the load back to the supply (e.g. when the grid feeds energy into a generator, causing it to 'motor'). In this case, the power factor isn't really negative, but simply appears to be so.

What shows a correlation which may be positive or negative between two sets of data?
I believe you are asking how to identify a positive or negative correlation between two variables, for which you have data. I'll call these variables x and y. Of course, you can always calculate the correlation coefficient, but you can see the correlation from a graph. An x-y graph that shows a positive trend (slope positive) indicates a positive correlation. An x-y graph that shows a negative trend (slope negative) indicates a negative correlation.
What is the difference between negative and positive plane in pcb design?
A positive plane is just like any other artwork layer - it shows where copper will be. A negative plane, like the name suggests, shows where there will not be copper.
A coordinate grid that shows both positive and negative numbers is sometimes called a?
Coordinate plane
What is the magnitude of negative 4?
its just 4. the negative shows its direction
Do galvanometer has positive or negative terminals?
Absolutely not. The reason behind is that it shows currents (both ac and dc) which has a desired direction of flow of electrons.. So Galvanometer does not have any electrolytic terminals!!
What are atoms OR groups of atoms with a positive OR negative charge?
a zewithalarion shows poth positive and negative; go figure...
Difference between negative health and positive health?
Negative health is a bad thing, it shows that there is regression. Positive health on the other hand, is a good thing. It shows improvement.

What is the role of the battery symbol in a circuit diagram?
The battery symbol in a circuit diagram represents a power source that provides electrical energy to the circuit. It shows where the positive and negative terminals of the battery are connected in the circuit, indicating the flow of current from the positive terminal to the negative terminal.

How do you type in minus numbers into a calculator?
Most calculators have a +/- (+ is positive, - is negative) symbol on them, which allows you to use the negative function. To do so, simply key in the number, then hit the +/- sign, which will then put the number in negative (minus) status. But if you already have a negative number, for example if you key in 25 - 30, you will have a -5, then you can hit the symbol to make it a positive number if that's what you want. In other words, when you hit that function, it will give you the opposite of what's in it at the time. For example, if the display shows a positive number and you hit that function, you will then have a negative number. If it shows a negative number and you hit that function, you will then have a positive number.
What is significance of correlation?
it shows any pattern that may emerge in any given set of date, this includes a positive or negative correlation. positive where a gradient goes from low to high negative where a gradient goes from high to low
How does refrigerated urine affect the levels on a drug test?
It will make everything level out. Stuff that does positive will be less visible and stuff that shows negative will look more positive
How do you differentiate between Rheumatoid Arthritis and Seronegative spondyloarthropathy?
For one thing Seronegative spondyloarthropathy shows a negative rheumatoid factor.
What positive and negative character traits does Odysseus show in his adventure with the cyclops?
positive- he shows outstanding wit by escaping the cyclops by blinding it then hiding on the undersides of the sheep negative- he shows stupidity by shouting his name out to the cyclops when he's escaping, this way the cyclops prays to his father, Poseidon, and makes it harder for Odysseus to go home
Is cellular respiration a negative or positive delta g?
Photosynthesis is a positive delta G as it produces more free energy than it uses. The overall result of the Gibbs equations shows that delta G is positive
