Step Potential is the potential Difference between two points on the earth's surface, separated by distance of one pace, that will be assumed to be one meter in the direction of maximum potential gradient (IS 3043) Touch Potential is the potential difference between a grounded metallic structure and a point on the earth's surface separated by a distance equal to the normal maximum horizontal reach, approximately one meter. (IS 3043)

What is the pitting potential give examples of factors which influence the value of the pitting potential?
Pitting potential is the potential where the pitting start and this is noticed when the current is suddenly increased that also mean below this value, now pitting corrosion will initiate Many parameters can effluence the pitting potential such as Temperature, halides ions, surface finishing of the alloy and also state of the electrolyte , is it flowing or stagnant.
What is the potential voltage?
Unless you are using 'potential' in the general sense (i.e. "What is the possible voltage?"), there is no such engineering term as 'potential voltage'. Voltage is a synonym for 'potential difference', so your expression would then mean "What is the potential potential difference?"Do not mix up 'potential' with 'potential difference' (voltage); they are two different things.
Why is the peak amplitude of voltage load lower than the amplitude of voltage transformer?
Unless otherwise stated, the value of an a.c. current or voltage is expressed in r.m.s. (root mean square) values which, for a sinusoidal waveform, is 0.707 times their peak value. The output of a voltage (or potential) transformer is no different, its measured voltage will be its r.m.s value which is lower than its peak value.
What is voltage potential betweei positive to earth?
By saying 'positive', you appear to be describing a d.c. system. In which case it depends entirely on the potential difference of the source and how it is earthed. If you are describing an a.c. system, then you presumably mean 'line', rather than 'positive', then -again- it depends on the potential difference of the source and how it is earthed -e.g. in the UK, the potential of the line, measured with respect to earth, should be close to the nominal value of 230 V.Incidentally, there is no such thing as 'voltage potential'. 'Voltage' is synonymous with 'potential difference', not'potential'. So, when you say 'voltage potential', it's the same as saying 'potential difference potential' which, I think you will agree, doesn't make any sense!
What does wcc gate valve mean?
WCC mean standard temp.
What is the difference between standard deviation and mean?
The mean is the average value and the standard deviation is the variation from the mean value.
What does a z-score of -1.5 mean?
z-score of a value=(that value minus the mean)/(standard deviation). So a z-score of -1.5 means that a value is 1.5 standard deviations below the mean.
Is the expected value the same as the standard deviation?
No. The expected value is the mean!
What does denominator of z-score measure?
The standard deviation.z-score of a value=(that value minus the mean)/(standard deviation)
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.
What is used to calulate potential energy?
Depends what potential energy you mean. Without an additional qualifier, "potential energy" frequently refers to gravitational potential energy. This is calculated as mass x gravity x height. If you want to use standard (SI) units, mass is in kg., gravity in meters per second square (the value is about 9.8, if you are close to the Earth's surface), and height in meters. The result is in Joule.Depends what potential energy you mean. Without an additional qualifier, "potential energy" frequently refers to gravitational potential energy.

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.
What does the standard error mean?
For a sample of data it is a measure of the spread of the observations about their mean value.
How is the z-score depicted?
z-score of a value=(that value minus the mean)/(standard deviation)
How do you find out the z-score?
z-score of a value=(that value minus the mean)/(standard deviation)
What is meant by a z-score?
z-score of a value=(that value minus the mean)/(standard deviation)
What is a T score in standardized testing?
T scores are also standardized norm scores, where the mean value is 50 and standard deviation value is 10, in contrast to Z scores where mean value is "0" and standard deviation value is 1. -Rama Reddy Karri
