1 00:00:01,250 --> 00:00:03,020 Hello and welcome. 2 00:00:03,020 --> 00:00:07,670 Today we'll talk about that is a store in more details. 3 00:00:07,670 --> 00:00:10,130 We will take a good look at this store. 4 00:00:10,170 --> 00:00:19,250 Defying all resistance defying resistance values OMB's colored code interpretation power dissipation 5 00:00:20,180 --> 00:00:26,890 and we will look at resistors and circuits serious battle and mix. 6 00:00:26,960 --> 00:00:31,220 This is there is a store symbol as we mentioned earlier. 7 00:00:31,220 --> 00:00:44,150 Now let's look at um the first thing with which is resistance defined resistance is the embodiment to 8 00:00:44,150 --> 00:00:53,000 the free flow of electrons through our conductor friction to moving electrons where there is friction 9 00:00:53,030 --> 00:00:57,190 there is he generated all materials except some resistance. 10 00:00:57,200 --> 00:01:01,560 Even the best of conductors unit measure in arms. 11 00:01:01,580 --> 00:01:10,890 So we measure resistance in arms from one divide by tens of arms to millions of on. 12 00:01:10,950 --> 00:01:14,730 Now let's look at resistor types. 13 00:01:14,950 --> 00:01:21,310 There's the VIX value the Variable value the combos aren't resistive material. 14 00:01:21,310 --> 00:01:29,460 The Wild One and Two barometers associated with the resistors which is the resistance value and arms 15 00:01:29,900 --> 00:01:32,610 both are handling capabilities in Watts. 16 00:01:32,640 --> 00:01:39,420 So these are the two most important factors that you must take care of. 17 00:01:39,420 --> 00:01:44,340 When I'm mentioning at a store or dealing with a resistor. 18 00:01:44,340 --> 00:01:52,040 Now if we looked here all hundred armed to the store this is a hundred on that one that one that one. 19 00:01:52,200 --> 00:01:56,030 They came in different sizes as you can see. 20 00:01:56,310 --> 00:02:00,060 So they can handle the different amount of power. 21 00:02:01,110 --> 00:02:10,830 As you can see the the diameter of each one is different than the other. 22 00:02:11,460 --> 00:02:17,910 But the order was all the same value which is a hundred thousand on. 23 00:02:18,050 --> 00:02:25,940 Now let's look at this and know the different sizes between composite and wire one resistor as you can 24 00:02:25,940 --> 00:02:35,060 see here composite types all of these stores could have the same resistance value even for their relative 25 00:02:35,060 --> 00:02:38,050 sizes vary widely. 26 00:02:38,090 --> 00:02:45,410 So as we mentioned in the previous example these all have the same resistance which is a thousand all 27 00:02:46,130 --> 00:02:48,030 but they come in different sizes. 28 00:02:48,050 --> 00:02:51,660 The same here now flocked here. 29 00:02:51,670 --> 00:02:56,430 This is a fixed resistor as you can see this is how it looks. 30 00:02:56,430 --> 00:03:02,830 And this is another shape while in valuable resource total potential means that as you can see here 31 00:03:03,160 --> 00:03:06,670 that we will use and most of the audio devices. 32 00:03:06,670 --> 00:03:08,120 This is how it looks. 33 00:03:08,120 --> 00:03:13,110 This is its symbol and this is how it looks at real life. 34 00:03:13,120 --> 00:03:19,460 Now what really Inside Out is a store as you can see here. 35 00:03:19,870 --> 00:03:21,290 This is at a store Auburn. 36 00:03:21,340 --> 00:03:31,150 There is a stomach tube a metal in the cab as you can see here and a coating to connecting wires and 37 00:03:31,150 --> 00:03:32,500 the two terminals. 38 00:03:32,590 --> 00:03:39,550 And here we can see the printed values and there is also color bands that represent the value of the 39 00:03:39,550 --> 00:03:40,750 resistance. 40 00:03:40,840 --> 00:03:46,830 If you don't have a bolt on me today you can know its value from the color bands. 41 00:03:46,840 --> 00:03:51,840 Now let's look at Reading resistor color codes. 42 00:03:53,010 --> 00:03:57,210 First you need to understand that each of these color has a meaning. 43 00:03:57,210 --> 00:03:59,940 The first one is the first band. 44 00:03:59,940 --> 00:04:04,120 This is the second band and this is the multiplier. 45 00:04:05,290 --> 00:04:09,750 And this is the tolerance. 46 00:04:09,790 --> 00:04:18,250 Now we need to model how to read that as this tool cannot code with any practice in a practice using 47 00:04:18,320 --> 00:04:21,430 one Columbus's term brown black red. 48 00:04:21,550 --> 00:04:28,950 And tolerance band let's look at that one come on resistor terms as a store. 49 00:04:29,560 --> 00:04:32,610 So gold or silver band is art right. 50 00:04:32,620 --> 00:04:40,660 So you need to lift that ban which will be either gold or silver and your right side right hand side 51 00:04:41,350 --> 00:04:45,080 not the color of the two left hand color bands which are here. 52 00:04:45,280 --> 00:04:47,560 The green line the blue one. 53 00:04:47,560 --> 00:04:51,090 The leftmost band is the left hand value digit. 54 00:04:51,220 --> 00:04:58,540 The next band to the right is the second value digit not the color of the third band from the left which 55 00:04:58,540 --> 00:05:05,380 is yellow here as you can see you must know its color. 56 00:05:05,380 --> 00:05:09,490 This is the multiplier multiple the two value digits by the multiplier. 57 00:05:09,580 --> 00:05:12,000 So we will get two digits from here. 58 00:05:12,010 --> 00:05:14,880 Then we will use this multiplier to multiple them. 59 00:05:15,820 --> 00:05:22,690 Um let's look at let's say a more solid example. 60 00:05:23,770 --> 00:05:30,830 But first let us uh look at this uh color codes. 61 00:05:31,390 --> 00:05:37,080 If it's black and existed in the first digit then its value will be zero. 62 00:05:37,120 --> 00:05:41,680 And so on for other cars until you reached the White one which is nine. 63 00:05:41,920 --> 00:05:45,070 If it's the second digit it will have the same value. 64 00:05:45,550 --> 00:05:53,110 While if any of these colors existed in the first band from the left it will be that multiplayer. 65 00:05:53,500 --> 00:05:56,990 As you can see one in hundred thousand. 66 00:05:57,340 --> 00:06:04,750 And depending on whether the right hand band is gold or silver you can add other lines of 5 percent 67 00:06:04,810 --> 00:06:09,390 or 10 percent or in case of no local band. 68 00:06:09,430 --> 00:06:14,420 It would be 20 percent this is a very symbol. 69 00:06:14,680 --> 00:06:24,180 So now let's look if we have one kilometer this tall brown black red and tolerance band let's orient. 70 00:06:24,180 --> 00:06:28,710 There is a story with the tolerance band to the right the gold or silver band. 71 00:06:28,710 --> 00:06:30,780 There is no band we mentioned. 72 00:06:30,780 --> 00:06:39,480 That would be 200 to 20 percent tolerance to this tour let's orient that resistance so the band are 73 00:06:39,480 --> 00:06:40,710 to all the left. 74 00:06:40,950 --> 00:06:46,170 Take note that the two significant digits of that is a total value are going to resented by the two 75 00:06:46,170 --> 00:06:48,630 left most color band. 76 00:06:48,660 --> 00:06:53,610 Note that the left most band is Brown which translates to a value of one. 77 00:06:53,670 --> 00:06:54,590 As you can see here. 78 00:06:54,600 --> 00:07:04,180 Brown means one and um well you must know that moving left to right. 79 00:07:04,210 --> 00:07:06,580 Note that the next band is black. 80 00:07:06,580 --> 00:07:13,050 Black means uh zero as we say as we can. 81 00:07:13,360 --> 00:07:16,280 Let's say this is the black one. 82 00:07:16,690 --> 00:07:18,730 It's the yellow. 83 00:07:18,860 --> 00:07:20,760 This is the second digit. 84 00:07:20,870 --> 00:07:23,270 So now continue moving left to right. 85 00:07:23,270 --> 00:07:29,680 Note that the multiplier band is red which translates to the multiple or multiply out of a hundred. 86 00:07:29,690 --> 00:07:36,640 So multiple that N times hundred it will equal 1000 or one kilo on. 87 00:07:36,740 --> 00:07:47,100 This is a really simple method to measure all different values of the stone with a fat as a store without 88 00:07:47,100 --> 00:07:48,810 using a digital multimeter. 89 00:07:48,810 --> 00:07:59,250 Now reading resistor color codes practical problem if we have an orange orange red yellow Violet orange 90 00:08:00,120 --> 00:08:09,660 brown black brown black brown black lean red red red blue gray or orange orange white orange I need 91 00:08:09,660 --> 00:08:12,140 you to get the value of all of these. 92 00:08:12,150 --> 00:08:22,920 Take a five to translate these values using this table I will applaud the course material so that you 93 00:08:22,920 --> 00:08:31,340 can use them you can use these slides to gain more knowledge the results will be three point three kilo 94 00:08:31,340 --> 00:08:42,310 arm 47 kilo on one hundred on one mega arm two point two kilo six sixty eight kilo thirty nine kilo. 95 00:08:42,690 --> 00:08:48,200 These boards that we use and solve this problem before going any further. 96 00:08:48,710 --> 00:08:53,400 And the next lesson we will discuss board the situation and out of the store. 97 00:08:53,480 --> 00:08:54,920 Thanks for watching. 98 00:08:54,920 --> 00:08:56,660 This is education engineering team.
