1 00:00:01,880 --> 00:00:02,590 Take a bus tour. 2 00:00:02,590 --> 00:00:08,750 Behavior in D.C. when exposed to D.C. the cab assault charges and holds the child as long as the D.C. 3 00:00:08,780 --> 00:00:10,320 voltage is applied. 4 00:00:10,570 --> 00:00:18,070 The capacitor essentially blocks DC voltage from busing through once the capacitor reaches full charge 5 00:00:18,190 --> 00:00:20,650 the following voltage equals the reverse Prussia. 6 00:00:20,800 --> 00:00:24,260 The current seizes to follow. 7 00:00:24,260 --> 00:00:25,100 It stops. 8 00:00:25,100 --> 00:00:34,010 It is essentially blocked the capacitor behavior in AC when AC current is applied during one half of 9 00:00:34,010 --> 00:00:39,650 the cycle capacitor accepts a charge in one direction during the next half of the cycle. 10 00:00:39,650 --> 00:00:46,630 The capacitor is discharged then the charge in the reverse direction during the next half cycle. 11 00:00:46,670 --> 00:00:48,480 The button reverses. 12 00:00:48,530 --> 00:00:56,950 Essentially it appears that AC current passes through a capacitor and this is going to be allowed to 13 00:00:56,950 --> 00:01:01,720 take it a little more explaining during the positive wash of the cycle. 14 00:01:01,720 --> 00:01:08,470 Electrons are drawn from that one and added to plate to the capacitor is charged with Blade 2 being 15 00:01:08,500 --> 00:01:13,740 negative and blade one being positive after a week of the positive cycle. 16 00:01:13,810 --> 00:01:20,910 The capacitor beings to this char begins to discharge when the cycle begins to go negative. 17 00:01:21,070 --> 00:01:28,390 Electrons are added to plate 1 and drawn away from plate to the cover stories charged with Blade 1 being 18 00:01:28,390 --> 00:01:30,820 negative and Blade 2 being positive. 19 00:01:31,420 --> 00:01:38,500 If the audience looks at just one blade the blade goes from positive to negative and back again just 20 00:01:38,590 --> 00:01:42,640 as if the blade where a source of AC. 21 00:01:42,910 --> 00:01:48,780 Now let's look at the cobblestone behavior a couple of blocks the passage of DC a carbon store buses 22 00:01:48,870 --> 00:01:49,910 AC. 23 00:01:50,680 --> 00:01:53,620 We need to to summarize this. 24 00:01:53,630 --> 00:02:04,420 Um it just blocks DC once fully charged while AC can pass through that capacitor let's look at capacitance 25 00:02:04,420 --> 00:02:11,910 value as you can see the unit of capacitance is the followed single followed is a huge amount of capacitance. 26 00:02:11,950 --> 00:02:21,370 Most electronic devices are cover stories that have a very tiny fraction of a fraud common capacitance 27 00:02:21,370 --> 00:02:38,740 ranges are micro nano Biko micro means uh then punishable by six and uh negative six nine or ten to 28 00:02:38,800 --> 00:02:47,440 the board of lines minus not nine Biko turned to the bar board of minus twelve and this is their sine 29 00:02:47,620 --> 00:02:56,650 micro nano and Biko now uh let's look at Western value the cluster and vacation depends on the Cluster 30 00:02:56,650 --> 00:03:06,070 type could be color bands dots or numbers wise to keep clusters organized and decide to prevent 0 2 31 00:03:06,070 --> 00:03:14,110 for trying to identify the value since their value can be really hard to calculate. 32 00:03:15,540 --> 00:03:24,490 As you can see here this is one hundred and eight plus two plus or minus two births and turnarounds. 33 00:03:24,540 --> 00:03:31,710 This is 104 Z and cholesterol notifications can be a little tricky and complicated these two illustration 34 00:03:31,710 --> 00:03:34,840 shows the typical numbering system. 35 00:03:35,280 --> 00:03:43,050 Some common example one may go forward uh is written by one hundred five point one microphone out is 36 00:03:43,050 --> 00:03:45,110 written by hundred. 37 00:03:45,240 --> 00:03:54,240 As you can see here born 0 1 Micro Four out the ten by one hundred three 1000 people four out equals 38 00:03:54,240 --> 00:03:59,870 one none of out equals one hundred two point zero for seven. 39 00:03:59,980 --> 00:04:02,140 Four out equals four. 40 00:04:02,190 --> 00:04:02,730 Seven. 41 00:04:02,730 --> 00:04:06,040 Three or four hundred seventy three. 42 00:04:06,570 --> 00:04:12,230 And born zero to two micro fraud equals four hundred twenty three. 43 00:04:12,300 --> 00:04:21,360 So it's a little bit tricky to read a capacitor value but you need to do your best or use that a sheet 44 00:04:21,420 --> 00:04:23,910 or simply use Google Search. 45 00:04:26,110 --> 00:04:33,200 Capacitor and circuits two physical factors affected by storage value blades spacing plates surface 46 00:04:33,260 --> 00:04:44,220 area in series blades are far apart making of a senseless charged place far apart as you can see here. 47 00:04:44,530 --> 00:04:46,310 These are two capacitors. 48 00:04:46,600 --> 00:04:56,580 They are treated like uh resistors and battery C1 multiple by C to divide by C one plus C two one. 49 00:04:56,740 --> 00:05:04,210 As you can see here capacitors and circuits in both the surface area of the blades add up to be greater 50 00:05:04,420 --> 00:05:05,400 and close together. 51 00:05:05,410 --> 00:05:13,000 As you can see here while here they are about the positive and negative. 52 00:05:13,090 --> 00:05:19,680 This makes the capacitance more the capacitor so the Bled area is more. 53 00:05:19,720 --> 00:05:25,770 This means the cluster is more so the total will be C1 plus C to. 54 00:05:26,040 --> 00:05:28,660 This is a symbol method. 55 00:05:28,800 --> 00:05:36,090 Another way to analyze this is to consider the capacitor as the reverse of that is a store that has 56 00:05:36,090 --> 00:05:39,870 a store and series equals one plus R2. 57 00:05:40,200 --> 00:05:47,820 While the US store in theory and series are the same as there is a store in barrier C one plus multiple 58 00:05:47,820 --> 00:05:52,900 by C to divide by C one plus C two. 59 00:05:53,070 --> 00:06:03,050 As you can see here here the above stores in battle see C1 plus C two what is a student but equal are 60 00:06:03,120 --> 00:06:10,900 one multiplied by R2 divided divide our one plus our two the surface area of the conductive blades in 61 00:06:10,900 --> 00:06:12,560 bottle cap capacitor. 62 00:06:12,640 --> 00:06:18,490 Add together the electrons on the blades connected the negative balls of the source breathe out across 63 00:06:18,490 --> 00:06:25,180 both combustible blades the positive change absence of electrons on the place attached to the positive 64 00:06:25,180 --> 00:06:33,490 wall of the source also is spread out the bliss are still only separated by the same distance as if 65 00:06:33,670 --> 00:06:40,390 there was just a single carbon source so there is more electrons are exposed over a greater surface 66 00:06:40,420 --> 00:06:49,980 but of the same distance therefore the capacitance will be more the symbol some That's it for capacitors. 67 00:06:50,010 --> 00:06:53,100 Next we will discuss in doctors and more details. 68 00:06:53,100 --> 00:06:54,360 Thanks for watching this. 69 00:06:54,370 -->
