What else can I help you with?
Is capacitor polarity sensitive?
Some capacitors are polarity sensitive; some are not. It depends on the design. Electrolytic capacitors, for instance, are polarity sensitive, while ceramic disc capacitors are not. You can generally tell, if the capacitor is marked with polarity signs, such as + and -, if it is or not.
How do you reverse polarity on ac motor?
Reversing polarity is not possible with an ac motor. Some do have wiring that will allow you to change rotation. The type and model of the motor can tell you if it is reversible.
What does the ( ) or (-) oxidation number tell you about an ion?
Its electric charge polarity. If (+) it is missing electrons, if (-) it has extra electrons.
What are two examples of polarity?
-- negative polarity -- positive polarity
What are the application of straight polarity arc welding?
AC (Alternating Current) and DC (Direct Current) is used to describe the polarity of the electric current that the welder generates and in what direction it travels. If you use the wrong polarity for a certain welding rod, your weld strength will not be very good. The general terms associated with polarity are reverse polarity and straight polarity. These are common to the welding trade. Another way to describe the two terms are electrode positive and electrode negative. Electrode positive is the same as reverse polarity. Electrode negative is the same as straight polarity. Hence the + and the - written on your welder where the cables connect to it. Any type of welding rod you buy will be labeled as to what polarity should be used for welding with it. Using the correct polarity will ensure the proper penetration and the over all look of the final bead. If you use the wrong polarity you can tell by the signs. There will be an excessive amount of spatter, you will have bad penetration, and you will have less control of your arc. Some welding machines have a switch to adjust the polarity. If your welder doesn't have one you will need to switch the welding cables around where they plug into the machine. If you want reverse polarity, you need to make sure the electrode holder is plugged into the + terminal. The easiest way to tell if you are using the wrong polarity is by the sound and the feel of the weld you are laying down. If you don't have much experience with stick welding you will have a little more trouble determining the difference. I have seen guys weld all day long with the wrong polarity. Then I would grab their welder to use for couple of minutes and I could tell right away. It all comes down to experience.
What problems are there with reverse polarity?
Reversing polarity ,changes the rotation of the device you are changing polarity on.
Does space have polarity?
No. Electromagnetic fields have 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.
How does a speaker polarity work?
a speaker polarity is sub mainframe of the ................................
Can you use the word polarity in a sentence?
the polarity of the battery is reversed
Why the resistor does not have polarity?
they do not have any electrical property that is polarity sensitive
Do integrated circuits have polarity?
Yes integrated circuits have polarity.
