Polarised capacitor vs. unpolarised capacitor. Which to use when?
$begingroup$ @TheRealJoe That is an excellent link provided except it does not explain why a polarized capacitor must be under the specified polarity. The need to do so was implied with the image of a failed electrolytic capacitor, as in the cap could fail in a puff of smoke and bits of metal if under too much reverse voltage.

Replacing Capacitors in Old Radios and TVs
Non-electrolytic capacitors are not polarized. Neither end is positive or negative. They have smaller capacitance values than electrolytics, anywhere from .0001 mfd to .5 mfd. Common values are .01 mfd, .02 mfd, and .05 mfd. Below are the common types of non
Which way to connect a capacitor?
Electrolitc capacitors have markings for the minus (- connection) most times there is a coloured band on that side. ... One important difference in polar capacitors is that electrolytic caps have the negative terminal marked, and tantalum caps mark the positive. Always be sure of the relative voltage differences of points with a capacitor ...
