Polarity is a term used to describe the direction of current flow. In an electrical circuit, the polarity of a voltage source determines the direction of current flow. The polarity of a current source determines the direction of voltage drop.
What polarity means in chemistry?
Polarity in chemistry refers to the distribution of electric charge across the atoms in a molecule. molecules can be either polar or nonpolar. Polar molecules have a net dipole moment, meaning that the positive and negative charges are not evenly distributed. Nonpolar molecules do not have a net dipole moment. What does polarity mean example? Polarity refers to the direction of electric current. For example, the positive pole of a battery is the one that gives off electrons, while the negative pole is the one that receives them. A circuit is said to be polarized if there is a potential difference between its poles.
What are the two types of polarity?
Polarity in electricity refers to the direction of the flow of electric charge. There are two types of polarity: positive and negative. Positive polarity occurs when the electric charge flows from the positive terminal of a power source to the negative terminal. Negative polarity occurs when the electric charge flows from the negative terminal of a power source to the positive terminal.
What is the opposite of polarity?
There is no definitive opposite of polarity, as the term can be used to describe a variety of electrical phenomena. In general, however, the opposite of a positive polarity would be a negative polarity, and the opposite of a negative polarity would be a positive polarity.
How do you determine polarity?
The polarity of a power system refers to the direction in which electric current flows. The current in a DC power system flows in one direction only, while the current in an AC power system alternates between positive and negative directions. The polarity of a power system can be determined by observing the direction of current flow in the system.
