Frequently asked questions

What is the difference between polarity and polarisation?

Polarity is the condition of having two opposite poles or extremes. Polarisation is the process by which something develops that condition or is pushed further towards the extremes. Public opinion has polarity; it becomes that way through polarisation.

What does reversing the polarity do?

It swaps the positive and negative connections. In a DC motor this makes it turn the other way; in many electronic devices it does nothing useful and can cause damage, which is why connectors are usually designed to fit only one way round.

Why is water a polar molecule?

Oxygen pulls the shared electrons more strongly than hydrogen does, so the oxygen end carries a slight negative charge and the hydrogen ends a slight positive one. That uneven charge is its polarity, and it explains why water dissolves salts and sugars so readily.

What is the meaning of polarity?

"polarity" (noun) means the property of having two opposite poles or charges, such as positive and negative in electricity or north and south in magnetism.
