Im not sure what u mean by RTD. But maybe this might help..\n\nhttp://www.answers.com/RTD

Wall sockets have AC voltages, so there is no positive and negative.  One of the two prongs has what is called "Hot", and the other is called "Neutral".  The Neutral is connected to ground back at a distribution center, while the Hot is 110 Volts AC (in the U.S.).  By the time it gets to your home, the Neutral is not quite ground anymore, but is still relatively safe- wheras the Hot is quite dangerous and potentially deadly.\n\nSome appliances are designed to have extra protection between the Hot and people.  For example, a light socket has the 'threads' (the easily touched part) connected to Neutral.  As another example, most appliances and the light switches disconnect the Hot when they are off.\n\nThe different sizes of the sockets prevent you from plugging an applicance in backwords.  If you did this, then the switch would disconnect the Neutral instead, and leave the Hot on- making the device less safe.

I agree with earlthek and babydoll. Electrical synapses in the body that affects the polar imbalance.

Hick_Ninja's answer is correct if as you say the current is flowing in one direction upward. The right hand rule will give you the answer. Here is an illustration of the right hand rule and how to apply it: http://hyperphysics.phy-astr.gsu.edu/hbase/magnetic/magfor.html\n\nIf however, you are using an Alternating Current, then the flow direction reverses with some frequency. The right hand rule will still work, but the field is reversing. Here is a good illustration of that:\nhttp://www.sunblock99.org.uk/sb99/people/DMackay/ac.html\n\nThe problem with clockwise and counterclockwise is that they are relative to point of view. So yes, it is counterclockwise in the horizontal plane, but only if looking down on it. Here's an illustration of that:\nhttp://hyperphysics.phy-astr.gsu.edu/hbase/magnetic/wirfor.html#c1

Go to your local hardware store and purchase a one of those small plug in circuit testers with the three LEDs. Plug it in and in less than a second, you will know exactly what is wrong (reverse polarity, open neutral, open ground, etc....) I think they cost around $3.50 - and they are very handy.\n\nBe sure to cut the power before attempting any repairs.\n\nI suspect you'll find that the three outlets are on the same line (circuit) and the originating plug has lost the neutral wire - just a guess based on 35 years experience.

Polarity of electricity was specified long ago by Benjamin Frankline before there was a practical means of detecting electrons.  He could have tossed a coin to specify + or -.  The thought was that electricity would flow (like water) from + (high) to - (low).  Unfortunately it was discovered that electrons actually flow from - to + in an external wire, but it was too late and we live with convention now.  In a way it really doesn't matter as long as all circuit designers agree on the convention since we can not see electrons; unless you are designing a vacuum tube (etc.) where electrons must physically flow from a heated element that boils them off to a grounded plate that collects them.  Cathode is normally the negative pole.

You should make sure that the neutral is not connected in the wrong neutral bar, because if it is connected in the neutral bar feedind of the rcd it will trip.\nYou must have crossed wires in the DB if your rcd is tripped

If the molecule has O,N,F,or Cl then most likely it is polar.  Look at the periodic chart and remember that the elements in the upper right are the most electronegative, so they want electrons.  When these elements are in a compound with other atoms such as C and H they will pull electrons closer making a dipole moment.  \n\nThe only real trick is looking at the geometry of the molecule, if there is more than one electronegative atom pulling in opposite directions then the dipole is canceld.  Such as O=C=O which is liniar.\n\nLook at an electronegativity chart you will see what I mean

To the first answer----WHAT? What does hydrogen bonds have to do with polarity? Ever heard of dipoles? Why do the need hydrogen bonds when the electronegativity is what is causing the polarity? Please, don't answer question you have no idea about. Anyone can look up stuff and copy and paste. NaCl  doesn't form hydrogen bonds but is VERY solube.\n\nNow, to answer the question. I think what you are eluding to by using "most," is the majority of them. What it boils down to is the molecule is too big. If you have like CH3-Cl, it is a small molecule and the polarity is spread of a small place, thus making it polar. Now, if you have something like C-C-C-C-C-C-C-C-C-C-Cl, the only part that is polar is the Cl part and the rest of the molecule is not, thus will not interact in water.

If the deflection surface has any diffraction or diffusion to it, the light may just be redirected imperfectly. 12kV? Jumpin Gigawatts!

A mag-levs route is lined with magnets and they use the polarity to move -- almost like a model or toy train; except this is done with magnets. They don't come in contact with anything though they do have retractable rubber wheels but those aren't used when they are moving.\n\nEDIT: P.S. Aproov -- anyone can copy and paste...\n\nThere's more info in the below link:

this is not true.  not at all.  my source is that i am a urologist, and i do not see much dextrocardia, but i do see it hanging on boths sides quite often.

It depends on what kind of mount you have, it seems you either have a German equitorial or an altazimuth mount.\nIf you are leveling & alighning on polaris and the blank end has a reference mark & 0 deg. north on the scale is in the center of two tripod legs the zero faces south.

or is it maximun voltage?\n\nlike terminal velocity is maximum speed...
