Dialogue: 0,0:00:11.66,0:00:22.41,Default,,0000,0000,0000,,>> Capacitors are devices that provide electrical energy storage of two types.
Dialogue: 0,0:00:22.41,0:00:31.66,Default,,0000,0000,0000,,One, where there's two conducting surfaces with an insulator between so that one side,
Dialogue: 0,0:00:31.66,0:00:34.47,Default,,0000,0000,0000,,when you apply a voltage to it,
Dialogue: 0,0:00:34.47,0:00:37.55,Default,,0000,0000,0000,,it can't get through the insulator,
Dialogue: 0,0:00:37.55,0:00:44.31,Default,,0000,0000,0000,,so it piles up as charge at every little atom on both sides,
Dialogue: 0,0:00:44.31,0:00:49.42,Default,,0000,0000,0000,,one plus and one minus, and stores energy.
Dialogue: 0,0:00:52.58,0:01:01.55,Default,,0000,0000,0000,,Polypropylene, when it's built in a manner where it's stretched in two sides,
Dialogue: 0,0:01:01.55,0:01:07.40,Default,,0000,0000,0000,,it comes out as a film, and then you stretch it both lengthwise and
Dialogue: 0,0:01:07.40,0:01:16.62,Default,,0000,0000,0000,,sideways to orient all the molecules in the direction of the surface of the film.
Dialogue: 0,0:01:17.93,0:01:23.68,Default,,0000,0000,0000,,Roll up the film and send it into the winding machines, so it wind
Dialogue: 0,0:01:23.68,0:01:32.12,Default,,0000,0000,0000,,it into with the aluminum foil we are making to make the capacitors.
Dialogue: 0,0:01:35.99,0:01:42.29,Default,,0000,0000,0000,,The other one was stored energy with the similar thing except that
Dialogue: 0,0:01:42.29,0:01:49.14,Default,,0000,0000,0000,,the insulator level is the metal oxide.
Dialogue: 0,0:01:49.14,0:01:54.98,Default,,0000,0000,0000,,The insulating film is deposited by anodizing aluminum,
Dialogue: 0,0:01:54.98,0:02:02.58,Default,,0000,0000,0000,,and you get very high capacitor levels with electrolytic capacitors.
Dialogue: 0,0:02:02.58,0:02:08.30,Default,,0000,0000,0000,,So, both tantalum oxide and aluminum oxide are
Dialogue: 0,0:02:08.30,0:02:17.93,Default,,0000,0000,0000,,very good preventers from electrons escaping their surfaces.
Dialogue: 0,0:02:17.93,0:02:20.03,Default,,0000,0000,0000,,That's what a capacitor is.
Dialogue: 0,0:02:20.03,0:02:24.27,Default,,0000,0000,0000,,It's a storage of electric charge.
