Does galvanometer have polarity?
No, a galvanometer does not have polarity. It is a device used to detect and measure small electric currents. The deflection of the needle in a galvanometer indicates the presence and direction of the current but not the polarity.
The polarity of an electromagnet is determined by what?
The polarity of an electromagnet is determined by the direction of the electric current flowing through the wire coil. Reversing the direction of the current will change the polarity of the electromagnet.
How do you induce polarity in galvanometer?
To induce polarity in a galvanometer, you can connect the positive terminal of a power source to one terminal and the negative terminal to the other terminal. This creates a potential difference across the terminals of the galvanometer, inducing polarity in the device.
Does critical mass depend on polarity?
No, critical mass does not depend on polarity. Critical mass is simply the amount of fissile material needed to sustain a nuclear chain reaction. Polarity, which is a property of molecules, does not play a role in determining critical mass.
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
What are two examples of polarity?
-- negative polarity -- positive polarity
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 speaker polarity work?
a speaker polarity is sub mainframe of the ................................
Do integrated circuits have polarity?
Yes integrated circuits have polarity.
Why the resistor does not have polarity?
they do not have any electrical property that is polarity sensitive
What is the polarity of C Cl14?
Its polarity is zero.CCl4 is non polar
Can you use the word polarity in a sentence?
the polarity of the battery is reversed
How do you use the word polarity in a sentence?
The polarity of both ends of a magnet is different. The positive and negative polarity exist for a magnet.
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.
Will changing the polarity of the current change the polarity of the electo magnet?
Yes!
What happen when the polarity of transformer reversed?
You cannot 'reverse' the polarity of a transformer -it is either wound with 'additive polarity' or 'subtractive polarity', and there's not much you can do about it! For a single transformer, its polarity doesn't really matter. But if you are going to parallel two transformers, then you must know the polarity of each transformer in order to avoid harmful circulating currents in their secondary windings.
