Capacitor Circuit Polarity. In other words the positive and negative dc source should be connected to the positive and negative terminals of the capacitor respectively. Pay close attention to this because if you plug a capacitor in a circuit the wrong way it may short circuit as in a current that is so large flows through the capacitor that can permanently damage it.

Traditional capacitors have markings such as a minus sign to indicate polarity. Both types possess two terminals.
The polarity of capacitors can be identified in several ways as follows.
The difference between these two types of capacitors is very simple. Some of the capacitors shown on this circuit board are standard electrolytic. They can be placed either way in a circuit. Electrolytic capacitors which are polarized are used in smoothing out ripples in dc.
