What is the difference between the watt hour meter and Var hour meter in terms of internal connection and work theory ie When the meter records watt-hour an when the meter records var hours?
Only watts (power) can produce work (energy) because of the phase relationship of the voltage and current in an alternating current, electric power system. With watts, the portion of the current and voltage that are in-phase with each other can do work. Vars, on the other hand are volt-amps reactive, which are out-of-phase with each other. Since Vars cannot do work, their existence in the electric power system is parasitic. The reactive current which flows in a power line, for instance uses a portion of line capacity, and also causes heating (I^2 * R power loss) due to the inherent resistance of the conductors. So, in the construction of a simple electromechanical meter, measuring Watt-hours or Var-hours, the respective current and voltage coils used to drive the rotating disk are situated to produce torque. For a Var Hr meter, the coils are rotated 90 degrees relative to each other to counter the lagging or leading phase shift and thus produce torque.
What is VAR?
Volt-Ampere Reactive. It is the reactive component of power when the Power Factor is less than unity (1.0). It is usually measured in KVAR - 1000's of VAR.
What do polygons represent on a map?
A polygon is very similar to a polyline. However, you have an additional option to set the interior fill color. We can draw a border around the state of Colorado (a nice rectangular state defined by simple latitude and longitude values) using the following code:Copy var points = [ new VELatLong(41,-102), new VELatLong(37,-102), new VELatLong(37,-109), new VELatLong(41,-109), new VELatLong(41,-102) ]; var outlineColor = new VEColor(0,0,255,1); var fillColor = new VEColor(0,0,255,.2); var outlineWidth = 5; var id = 'Colorado'; var poly = new VEPolygon(id, points, fillColor, outlineColor, outlineWidth) map.AddPolygon(poly);
What is the scientific name for snow pea?
Pisum sativum L. var. Saccharatum. :)
When does Daylight Saving Time go in effect?
function Init() { if(window.location.search.indexOf("pf=pf") >= 0) { var hostname = window.location.hostname; var firstDotFromRight = hostname.lastIndexOf( '.', hostname.length ); var start = hostname.lastIndexOf( '.', firstDotFromRight - 1 ); var domain = hostname.substr( start + 1 ).toLowerCase(); if (("live.com" domain)) { document.domain = domain; } } } Daylight time begins in the United States on the second Sunday in March and ends on the first Sunday in November. On the second Sunday in March, clocks are set ahead one hour. The first Sunday in November, clocks are set back one hour.

How many var is 1 square meters?
The unit var or vara is a length surveying unit, originating from Spain. In most surveys, it is equal to 33 1/3 inches. Nevertheless, it cannot be converted to a squaremeter, which is a unit of area, not length. See related question.
Why VAR meter does not measure real and apparent power?
A VAr meter only measures the reactive (imaginary) power. Apparent power is a combination of real and reactive power; thus having a VAr meter will not suffice to measure apparent power. Likewise, because the VAr meter only measures reactive power, it does not provide any information on real power.
