How is the polarity of a resistor determined?
Resistors do not have a polarity. BY DEFINITION, a resistor is a device that follows Ohms law, and does so regardless of the polarity in which it is inserted into a circuit. Manufacturers of resistors do all they can to make their resistors follow that definition. One way to make a resistor have no polarity is to build it so that it is mechnically symmetrical about its two leads. Doing so will ensure that it will also be electrically symmetrical, and thus non-polarized
Explain welder polarity?
Welder polarity has to do with DC (Direct Current) welders. Essentially, polarity is the direction of the current. Straight polarity means that the current is running from the electrode, to the metal, and back through the grounding clamp. Reverse polarity means that the current is going the opposite way, from the grounding clamp, through the metal, and up through the electrode.
What rule is used to find out polarity of a current carrying solenoid?
right hand rule is used to find out the polarity of current
What are particles with reversed magnetic polarity?
Antimatter
Do waves have magnetic polarity?
No, waves do not have magnetic polarity. Waves are disturbances or vibrations that propagate through a medium or space, and they do not possess magnetic properties. Magnetic polarity is a characteristic of magnetic materials such as magnets, where they have a north and south pole.
What is polarity definition for kids?
opposites attracting, like a magnet.

What is an example of polarity?
The definition of Polarity is -The uneven distribution of charges across a molecule -.so examples of polarity would be *water molecule with 2 positive hydrogen atoms and 1 negative oxygen atom *left hand and a right hand *east and west -.it's basically anything that is opposites
What are two examples of polarity?
-- negative polarity -- positive polarity
How does a drawing of polarity water and the bond polarities make a major contribution to the overall molecular polarity look?
The polarity is a vector quantity. The resultant of the polarity of bonds determines the polarity of the molecule. In CO2 there is polarity between the two C-O but the polarity is equal and opposite in direction so CO2 doesn't have polarity. If the polarity of bonds is not cancelled then the polarity remains in the molecule.
Why is a dipole similar to water?
The molecular structure of water allows foræthere to be a positive and a negative region, a dual polarity, which is the very definition of dipole.
Define alternating current definition?
The alternating current refers to the flow of the electric charge periodically and in the opposite direction. The polarity changes with the time..
Is unequal sharing of electrons acidic basic or polarity?
Polarity
How do appliances work if AC reverses direction?
AC current alternates polarity back-and-forth continually, by definition. Therefore, it is not possible to reverse AC direction. It is DC current that is directional such that when it's polarity is reversed the motor responds by turning in the opposite direction.
What is an audio inverter?
it invert the polarity of the in/out of the device. Inverter by definition invert one form to another form of energy [minus loss] so it can be used.

What problems are there with reverse polarity?
Reversing polarity ,changes the rotation of the device you are changing polarity on.
