Yes.
Electrons always flow from the negative pole to the positive pole. In a Direct current(DC) circuit, one pole is always negative, the other pole is always positive and the electrons flow in one direction only. In an alternating Current (AC) circuit the two poles alternate between negative and positive and the direction of the electron flow continually reverses.
In DC circuits (e.g. for a battery) positive is usually marked red and negative is usually marked black, but other color schemes are very common in automotive and telecommunications systems.
In AC systems which are at no point connected to earth (unlike domestic mains wiring where the neutral is commonly earthed at substations and generators) polarity is not important as the two wires alternate polarity many times per second.

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
Do ac capacitor have positive and negative polarity?
both
What are the 2 ways to find out which is the positive leg and which is negative - led?
On an LED, one leg will be shorter than the other. The shorter leg is the negative polarity.
Is the black wire on a lamp connection plus or minus?
The color of the wire does not indicate its polarity. In electrical systems, the polarity is typically designated as positive (+) and negative (-) rather than plus or minus. To determine which wire is positive or negative on a lamp connection, you would need to consult the manufacturer's instructions or use a multimeter to check the voltage.
What is a negative - positive?
Negative * positive = negative Positive * positive = positive Negative * negative = positive
What are two examples of polarity?
-- negative polarity -- positive polarity
Is ethanol positive or negative polarity?
goes from negative to positive
What does negative polarity mean with electricity?

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
Differentiate between the terms reversed polarity and normal polarity?
Normal polarity is for the power to normally go from positive to negative, reverse polartity is to change the positive to a negative and the negative to a positive so the power goes the other way.
Do potentiometers have polarity?
no there is no consideration of positive or negative legs in case of resistor.
Do transisors have polarity?
Basic transistors have three lead contacts that do have polarity . There are two kinds referred to as P-N-P (for positive-negative-positive leads) and N-P-N (for negative-positive-negative leads).
Do ac capacitor have positive and negative polarity?
both
The polarity of an eletromagnet is determined by the?
the way in which the positive & negative terminals on the battery or power supply are attached to the electromagnet. switching the leads from the positive terminal to the negative one, and the negative one to the positive terminal should reverse the polarity of your electromagnet.
What is the definition for polarity?
'Polarity' has a number of meanings, generally involving the distinction between positive and negative.
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.
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 is the difference between a positive limiter and a negative limiter?
The polarity at which it limits a waveform.
