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
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.
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
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..
What are two examples of polarity?
-- negative polarity -- positive polarity
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 is inverted audio?
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.
Does space have polarity?
No. Electromagnetic fields have polarity.
What is the definition of polarity?
Polarity refers to the existence of two opposite or contrasting tendencies or characteristics. In chemistry, polarity refers to the separation of electric charge leading to the presence of positive and negative ends in a molecule.
