linearly polarized
An electrical insulator that can be polarized by an external electric field.
Electrolytic capacitors tend to explode when connected to AC or to DC currents of the wrong polarity. The plates short out because the dielectric is maintained by a polarized field, and is then destroyed by the wrong polarity.
It is because when a dielectric is placed between the charges , the dielectric gets polarized and the net electric field between the two charges decreases, hence force = charge x electric field also decreases. john
That will depend on the dielectric. There will be two main effects - any change in the permeativity of the dielectric, and thermal expansion which will increase the distance between the plates. There will also be an change (probably an increase), in leakage current through the dielectric. Any change is very likely to be small or insignificant - I have worked in a factory making capacitors and temperatures were very variable, not controlled, for measurements of capacitance.
All electrolytic capacitors (e-caps) are polarized capacitors whose anode electrode (+) are made of a special metal on which an insulating oxide layer originates by anodization (forming), which acts as the dielectric of the electrolytic capacitor.
Polarized
For analog application that need swinging signal from positive to negative that will not work for you. But for DC applications where signal is always positive (or negative) that will be ok to exchange the capacitors with no harm to your circuit. Hope that will help you, if you need to find good quality electronic components i advise you to check www tmartis com, you can find a lot of good stuff there.
Not all pairs are. You have to buy Polarized lenses for them to be polarized.
is s.c.r polarized
For an insulating material dielectric strength and dielectric loss should be respectively
dielectric constant
