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.
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 does kinet ic potentila energies mean?
Kinetic potential energy is not a standard term in physics; however, it may refer to the energy associated with the motion of an object (kinetic energy) and its position within a gravitational field (potential energy). Kinetic energy is the energy an object possesses due to its velocity, while potential energy is related to its height and the gravitational force acting on it. The total mechanical energy of a system is the sum of its kinetic and potential energies.
What does wcc gate valve mean?
WCC mean standard temp.
What does SDR mean in pipe?
standard dimension ratio
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 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 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)
How is the z-score depicted?
z-score of a value=(that value minus the mean)/(standard deviation)
What is the average distance of each data value from the mean?
The 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
