00:00:00.000 [Music] 00:00:15.76000:00:15.770 okay so resistors have a color code 00:00:18.98000:00:18.990 value as we saw before and we read it 00:00:22.31000:00:22.320 from left to right like we read or words 00:00:25.75900:00:25.769 all right so this one's red red brown 00:00:29.00000:00:29.010 gold okay now the first two are going to 00:00:33.41000:00:33.420 be actual numbers so this will be a 00:00:35.51000:00:35.520 number this will be a number the third 00:00:37.52000:00:37.530 one the brown represents a multiplier 00:00:40.28000:00:40.290 and the gold represents a tolerance and 00:00:44.09000:00:44.100 we're gonna use a chart that looks like 00:00:45.41000:00:45.420 this and you'll have one attached to 00:00:47.02900:00:47.039 your activity all right so we don't have 00:00:49.22000:00:49.230 a third digit so I'm just gonna so we 00:00:55.72900:00:55.739 have a red red brown gold so red red is 00:01:02.66000:01:02.670 to the second one red is another two and 00:01:10.09000:01:10.100 our multiplier is Brown so Brown is 00:01:14.66000:01:14.670 times ten so 22 times 10 is 220 Oh so 00:01:22.31000:01:22.320 resistance is measured in ohms 220 ohms 00:01:26.09000:01:26.100 now let's talk about the gold band the 00:01:28.64000:01:28.650 gold band 00:01:29.53900:01:29.549 alright Gold is a tolerance this is gold 00:01:32.71900:01:32.729 my colors kind of wonky I printed out 00:01:35.14900:01:35.159 weird is 5% so plus or minus 5% okay so 00:01:43.52000:01:43.530 plus or minus 5% so red red brown gold 00:01:49.91000:01:49.920 is 2 2 times 10 22 times 10 which is 220 00:01:54.35000:01:54.360 ohms plus or minus 5% and that is how we 00:01:58.13000:01:58.140 read this resistors value and this is 00:02:00.80000:02:00.810 quick and this is 00:02:02.93000:02:02.940 really fast but that's alright let's do 00:02:05.00000:02:05.010 one more resistor okay so we're looking 00:02:08.66000:02:08.670 at the gold band last all right this 00:02:13.49000:02:13.500 one's brown black orange gold so Brown 00:02:16.28000:02:16.290 is one black is zero times 00:02:26.11000:02:26.120 orange orange orange oranges one 00:02:29.15000:02:29.160 thousand times a thousand there's gonna 00:02:32.21000:02:32.220 be ten thousand ohms our tolerance the 00:02:37.79000:02:37.800 gold band our tolerance is 5 so plus or 00:02:42.62000:02:42.630 minus 5 percent okay so that's a really 00:02:47.93000:02:47.940 quick way of how to read a resistor 00:02:50.30000:02:50.310 you'll have the chart to go by so we 00:02:53.84000:02:53.850 read from left to right first color is a 00:02:56.57000:02:56.580 number second color is a number third 00:03:03.71000:03:03.720 color is a multiplier 00:03:06.83000:03:06.840 well we multiply that first number by 00:03:08.99000:03:09.000 the first and second number by and the 00:03:12.50000:03:12.510 last number or the last band is the 00:03:15.86000:03:15.870 tolerance okay okay now we're going to 00:03:21.05000:03:21.060 talk about capacitors okay this is a 00:03:23.47900:03:23.489 capacitor this is actually what we call 00:03:25.58000:03:25.590 an electrolytic capacitor it actually 00:03:30.77000:03:30.780 tells you what the value is right there 00:03:36.38000:03:36.390 a hundred microfarads that's it 00:03:39.62000:03:39.630 that's how you read an electrolytic 00:03:41.97900:03:41.989 capacitor value it tells you hundred 00:03:45.86000:03:45.870 Ference or micro farad's all right easy 00:03:48.68000:03:48.690 enough right so then we get to these 00:03:50.44900:03:50.459 little guys this is a ceramic capacitor 00:03:53.36000:03:53.370 a ceramic disc capacitor and what we do 00:03:56.21000:03:56.220 for them is we look at the number that's 00:03:58.67000:03:58.680 on it so this one says 104 okay 00:04:03.61000:04:03.620 the first digit is the first figure so 00:04:07.19000:04:07.200 we got a 1 the second digit is the 00:04:11.54000:04:11.550 second figure so then we 00:04:12.92000:04:12.930 have a zero okay so right now we're at 00:04:16.49000:04:16.500 ten and then the third digit is the 00:04:19.24900:04:19.259 number of zeros after that number so we 00:04:24.20000:04:24.210 have a number and then we add let's see 00:04:26.29000:04:26.300 what's it say four four zeros one two 00:04:30.80000:04:30.810 three four so this is a hundred thousand 00:04:35.43900:04:35.449 pico farads ceramic capacitors are 00:04:39.05000:04:39.060 always in pico pico farads all right 00:04:43.15900:04:43.169 cool that's it we're done 00:04:45.52900:04:45.539 so first number is an actual number 00:04:48.17000:04:48.180 second number is an actual number and 00:04:49.96900:04:49.979 last numbers how many zeros you add so 00:04:53.02900:04:53.039 ten there's what we had and then we 00:04:55.24900:04:55.259 added four zeros afterwards and ceramic 00:04:59.08900:04:59.099 capacitors are measured in pico farads 00:05:02.21000:05:02.220 remember that ceramic capacitors the 00:05:04.55000:05:04.560 ones that look like these are measured 00:05:06.29000:05:06.300 in pico farads that's it we're done
