The unit of electric potential difference between two points is?
You can compare 'potential' with height, and 'potential difference' with the difference in height.The height of an object depends upon from where you measure it. For example an object three-quarters of the way up a 1000 m mountain is +750 m from the base of the mountain, but -250 m from the top of the mountain. Note how we apply a positive or a negative sign to indicate whether we are measuring upwards or downwards.The same applies to potential. It's value depends upon from where it is measured. For example, two charged objects could have a potential of , say, +5 V with respect to earth (ground) and a potential of -15 V with respect to earth. But the potential difference between them will be +5 - (-15) = 20 V.Notice how, in the above example, we always show a positive or negative sign when we talk about potential, but we don't use these signs when we talk about a potential difference. Furthermore, it is important that we must ALWAYS specify the reference point when we describe potential -e.g. "What is the potential at point A, with respect to (say) earth?"Taking this further. It's important to know that the term 'voltage' means 'potential difference', and not'potential'! It would be quite wrong to say that the 'voltage of an object is (say) -200 V with respect to earth'. The correct expression would be the 'potential of an object is -200 V with respect to earth'.
What is the importance of standard units in daily life?
standard unit is very important because it contains the same value,quantity and ect all over the world
How is motion demonstratd with snowboarding?
Snowboarding demonstrates speed, velocity, and acceleration. It can also demonstrate a positive or negative value for velocity and acceleration.
Convert standard cubic meter gas to Giga joules?
How do you write twenty-seven thousandths in standard form?
Twenty-seven thousandths (0.027) in standard form is: 2.7 × 10-2
Why the dc average voltage is having negative value?
Voltage is synonymous with 'potential difference', and cannot have a positive or negative value (in the sense of charge). So what you are describing is 'potential', which can. So, for example, a battery whose positive terminal is earthed or grounded will indicate a negative potential if a voltmeter is connected between earth and its negative terminal.
What characterizes depolarization the first phase of the action potential?
The membrane potential changes from a negative value to a positive value
What does the negative sign on the value of an enthalpy of formation indicate?
A negative enthalpy of formation indicates that energy is evolved.
Why inductance value is negative?
Inductance is not negative. It is measured in henrys, and that is a positive value. Inductive reactance, however, is measured in ohms, and is commonly shown as negative to indicate that the current lags the voltage.
Can The standard deviation of a distribution be a negative value?
No. The standard deviation is not exactly a value but rather how far a score deviates from the mean.
Can standard deviation value be less than 01?
Yes, it can have any non-negative value.
What does a negative z-score mean?
z-score of a value=(that value minus the mean)/(standard deviation). So if a value has a negative z-score, then it is below the mean.
Why in the standard potential for an oxidation reduction reaction not multiplied by the coefficient?
Because standard potential is not an additive property. That is, the standard potential for a reaction will always been a certain value, no matter if you have one mol or a billion mols. Each mol has the same potential and undergoes the reaction independent of all the other mols.
How do you find the voltage at a point in a circuit with respect to a negative voltage?
First of all, 'voltage' means potential difference -and you cannot have a potential difference 'at a point'. Similarly, you cannot have a 'negative' potential difference, so it doesn't make sense to talk about a 'negative voltage'.Your question, therefore, should read: 'How do you find the potential at a point in a circuit with respect to a negative potential?'The answer is that you simply connect a voltmeter between the two points. The reading will give you the value of the potential. If it reads upscale, then it'll be positive; if it reads downscale, then it will be negative (i.e. even more negative tan the reference potential).
Can Standard Deviation be greater than 100?
Yes. It can have any non-negative value.
If we have a positive value on a y intercept do we move up or down Where do we move for a negative value?
The standard set up would be to move up for positive values and down for negative.
What are all the values that a standard deviation s can possibly take?
Any non-negative value.
