The polarity of a circuit is dependent upon the type of circuit. Direct current circuits have one negative pole and one positive pole and they flow in one direction. Alternating current circuits the electron flow reverses because the tow poles alternate between negative and positive.

What is the necessary to know the polarity of voltage drop across a resistance?
Sometimes it isn't.Another AnswerVoltage drops don't have polarity in the sense of a positive or negative charge. The term 'polarity', when applied to voltage drops, describe the sense or the direction in which that voltage drop is acting within the circuit. The rule is that a voltage drop always acts in the opposite direction to the current which causes it. An example of when it's necessary to know the polarity (direction) of a voltage drop is when applying Kirchhoff's Laws or other network theorems to solve a circuit
How do you position the test equipment into the circuits ensuring the correct polarity and without damaging the circuit components?
Lick your own bum
How do you fix reversed polarity in a home inspection?
reversed polarity in an electric circuit, means whoever was doing the wiring had no knowledge of wiring. reversed polarity means that wires ( mostly on outlets) are incorrect. the black wire goes on the gold screw, the white goes on the silver one & the bare wire goes on the green screw. most home centers have a library of how to books. they average around $20.00 each.
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.
What is polarity protection in trunk circuit in telephone?
A bridge rectifier circuit used to convert A.C to D.C. and can also be used as a polarity protection circuit. Because irrespective of which of the input terminals is given +ve voltage , the output voltage is +ve at only one output terminal. hence polarity protected.
What will happen if you change polarity in parallel circuit?
The current in each branch of the circuit will turn and flow in the other direction.
99 beetle heat fuse reverse polarity?
i don't believe you can reverse the polarity on a fuse, they simply regulate the amperage of the circuit they protect,
What does negative polarity mean with electricity?
Polarity is the direction of flow of electrons throughout a circuit. There are two types of polarity: positive and negative. Postive polarity is of older circuits which means electrons flow from positive to negative. Negative polarity is of more modern circuits and that is the flow of electrons from negative to positive such as on car batteries
What is mean polar?
What is meant by polarity? Answer An electric charge has a polarity of either positive or negative. Also a voltage has a polarity, in that it could be positive or negative, with respect to some other voltage, such as the one at the other end of a battery or electric circuit.
What test would identify a short circuit in a lighting circuit?
earth continuity insulation resistance polarity
Important of polarity sign when recording the value of current?
'Polarity' as it applies to currents and potential differences in a circuit refers to the directions in which these quantities act. It becomes important if, for example, you are using Kirchhoff's Laws to solve a complex circuit.
What are three reason why a simple circuit may not work?
The circuit may not be complete. The power source may not be sufficient. The polarity of the battery is messed up.
What is polarity in welding?
Polarity in welding has to do with the direction of the current in the welding process. With direct current (DC) the welding circuit can either be straight, or reverse polarity. When the machine is set for straight polarity, the current flows from the electrode to the weld surface and creates considerable heat in the metal. When the machine is in reverse polarity, the current is backwards and is flowing from the metal to the electrode causing a grater concentration of heat at the electrode.

Why should a polarity test be conducted out on a lighting circuit?
to make sure the protection device such as fuse are connected at the live part
Can a magnet destroy an IC?
No a integrated circuit IC for short is solid state and can only be destroyed by reverse polarity or shortened output or to high input tension or current No a integrated circuit IC for short is solid state and can only be destroyed by reverse polarity or shortened output or to high input tension or current
