spectrum analyser is single channel and cannot find ratio of phase and magnitude
If you take two different nodes in a network and if you find the difference in voltage for those nodes then it is known as potential or voltage difference. Here the reference is not taken. But if you find potential difference between a node and its respective ground it is known as voltage at that node here reference is ground potential i.e zero.Answer'Voltage' is synonymous with 'potential difference'; they both mean the same thing. And it is important that these terms are not confused with 'potential'. So, it is incorrect to say 'voltage difference' (which would mean 'potential difference difference'!), or to describe a voltage as existing 'at' a particular point, or 'with reference to', for example, earth or ground.In very simple terms, if two points are at different potentials, then there is a potential difference (or 'voltage') between them. A potential exists when work is done moving a charge to a particular point; the greater the work, the higher the potential. 'Potential' is roughly equivalent to the potential energy gained by an object when it is lifted against the force of gravity.Think of it this way: 'potential' is equivalent to 'height', whereas 'potential difference' (voltage) is equivalent to the difference between points at different heights.
From what I can remember it's: |R(measured)-R(real)|/(R(real))*100%
disandvantage:-the wheatstone bridge is not applicable for high resistances advantage:-1)it shows a null measurement(i.e.-potential difference across the end points of the bridge is zero) 2)since it is an arrangement of 4 resistors ...it is useful to find one of them in terms of other 3
An EKG technician salary can range from anywhere between $50,000 and up. The best way to find out how much an EKG technician salary is would be to visit a local newspaper site.

You have to convert them to Polar Points or the Azimuth points and use the angle difference.
The angle between the direction your compass points and the direction you're facing is the 'magnetic azimuth'. The angle between the direction to the north pole and the direction you're facing is the 'true azimuth'. They are virtually never the same angle. The difference between them is the 'magnetic declination' or the 'compass declination' in the place where you are at in which.
In order to calculate Azimuth with google Earth one would need to figure the decimals of degree units that are used and find the direction of point A to B. Once the calculation has been made one can then decipher the amount of space between points A and B.
