Which resistor network has polarity bussed or Isolated?
bussed
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.
Do integrated circuits have polarity?
Yes integrated circuits have polarity.
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.
Why resistor should disconnected from the circuit when measured the value of resistor?
if not disconnected you will measure the resistance of the circuit in parallel with the resistor.
Do potentiometers have polarity?
no there is no consideration of positive or negative legs in case of resistor.
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.
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 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!

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).
How you calculate the polarity of voltage source across the resistor when two voltage sources are connected?
A: by using thevenin theorem
Why resistor do not have positive or negative terminal?
cuz a resistor is basically a long wire , that resists some of the charges flowing across it. it has resistive properties which stops some of the current from flowing from one terminal to the other. so....as it is just a piece of wire....it doesn't need a +ve or a -ve terminal
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.
