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

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.


The what of an electromagnet is determined by the direction of current flow?

The polarity of an electromagnet is determined by the direction of current flow. When current flows one way, the magnetic field is oriented in one direction, and when it flows the other way, the magnetic field is oriented in the opposite direction.


How can a polarity of an electromagnet be determined if the direction of current flow is known?

The polarity of an electromagnet can be determined by the right-hand rule. If the direction of the current flow is known, curl your right hand fingers in the direction of the current flow. Your thumb points in the direction of the north pole of the electromagnet.


How can the polarity of an electromagnet be determined if the direction of current flow is unknown?

The polarity of an electromagnet can be determined using the right-hand rule: wrap your fingers around the coil in the direction of the current flow (conventional current flow is from positive to negative), with your thumb pointing in the direction of the magnetic field. The side of the coil where your thumb points is the north pole of the electromagnet.


How is it that the dipole moment of HCl is determined?

The dipole moment of HCl is determined by calculating the product of the charge difference between the hydrogen and chlorine atoms and the distance between them. This results in a vector quantity that represents the polarity of the molecule.

How are the plus and minus voltage signs determined for resistors?

Resistors have no polarity. The voltage across a resistor is determined by the direction of current flowing through that resistor (and vice versa).


Why the resistor does not have polarity?

they do not have any electrical property that is polarity sensitive


Is it possible that the resistor will revert in position?

yes simply because resistor doesnt have polarity ^^


Which resistor network has polarity bussed or Isolated?

bussed


Does thermistor have polarity?

No, they have no polarity. They are just like a resistor in terms of polarity, and they allow to measure temperatures because their resistance varies with temperature in a predictable way.


What law is used to find the polarity of resistor when two voltage source are connected?

Hi! Well, it depends what voltage is "pushing" harder on the resistor. If you are ONLY dealing with 2 voltage sources and a single resistor, then the voltage source with the higher potential (or voltage) will dictate what polarity the resistor is. Cheers!

Do potentiometers have polarity?

no there is no consideration of positive or negative legs in case of resistor.

Does it matter which way a emitter resistor is installed?

A resistor is not polarity sensitive, and may be installed in either direction. That's why resistors don't have pluses ( + ) or minuses ( - ) printed on them.


How you calculate the polarity of voltage source across the resistor when two voltage sources are connected?

A: by using thevenin theorem


What is the relationship between bond polarity and molecular polarity?

The relationship between bond polarity and molecular polarity is that the overall polarity of a molecule is determined by the polarity of its individual bonds. If a molecule has polar bonds that are not symmetrical, the molecule will be polar overall. If a molecule has nonpolar bonds or symmetrical polar bonds that cancel each other out, the molecule will be nonpolar overall.
