Does it matter which way capacitor goes?

Keeping this in view, does it matter which way you connect a capacitor?
Any voltage rating (WVDC) will do. Connectthecapacitor momentarilly to a standard D-cell, C-Cell orAA-Cellbattery with the cap's negative lead connectedtothe negative terminal of the battery andthecap's positive lead to the battery's positiveterminal.Quickly connect the capacitor to a DVM oranalogvoltmeter.
Similarly, what happens if you connect a capacitor the wrong way? If the polarity is reversedwhileconnecting, the dielectric in the form of oxide layerisdamaged. A heavy current flows, large amount of heat isgenerated,and capacitor is damaged. An explosion can resultifit not provided with safety againstexplosion.
Also Know, which side of the capacitor is positive?
The majority of electrolytic capacitorsarepolarized types, that is the voltage connected tothecapacitor terminals must have the correct polarity,i.e.positive to positive and negativetonegative.
Is a capacitor directional?
They're also the only type of capacitor thatispolarized, meaning that they will only work when wired inaparticular orientation. On these electrolyticcapacitors,there's a positive pin, called the anode, and anegative pin calledthe cathode. The anode always needs to beconnected to a highervoltage.
