00:00:11.990 hi everyone I'm sorry if you're watching 00:00:14.62900:00:14.639 my video you've done difference or these 00:00:16.97000:00:16.980 heard of capacitors and now super 00:00:20.26900:00:20.279 capacitors so for science today we're 00:00:23.00000:00:23.010 going to tear one of each apart one is 00:00:25.27900:00:25.289 going to be a 16 volt 2200 farad record 00:00:29.59900:00:29.609 electrolytic capacitor another one is 00:00:32.15000:00:32.160 one of the two point seven volt 500 00:00:34.97000:00:34.980 farad green caps let me move the camera 00:00:38.78000:00:38.790 on over and we'll start unwinding and 00:00:40.61000:00:40.620 see what we find 00:00:41.42000:00:41.430 on the Left I got the regular 00:00:44.27000:00:44.280 electrolytic capacitor that's what's 00:00:46.36900:00:46.379 left of the case the top of it and the 00:00:49.25000:00:49.260 actual coil of material inside of it on 00:00:54.41000:00:54.420 the right I got the super cap opened up 00:00:57.86000:00:57.870 and this has also got a big coil so 00:01:01.34000:01:01.350 let's start with the regular capacitor 00:01:04.18900:01:04.199 just sort of one knows what it looks 00:01:06.14000:01:06.150 like 00:01:16.39900:01:16.409 there's your two electrodes it keeps all 00:01:18.67900:01:18.689 going inside this looks like just like 00:01:23.48000:01:23.490 any other one you got two metals 00:01:25.57000:01:25.580 separated by an insulator some sort of 00:01:29.45000:01:29.460 paper II wax paper or something and that 00:01:33.49900:01:33.509 is the standard regular electrolytic 00:01:36.38000:01:36.390 capacitor chances are I probably a 00:01:37.94000:01:37.950 little bit of moisture on my hands from 00:01:39.80000:01:39.810 the stuff so I better clean my hands 00:01:41.18000:01:41.190 real quick now for the super cap see if 00:01:45.85900:01:45.869 I can get this one 00:01:46.82000:01:46.830 nicely unwound here with my razor blade 00:01:52.18000:01:52.190 looks like this is the beginning right 00:01:54.20000:01:54.210 here 00:01:59.79000:01:59.800 we go it's got like a paper to it and 00:02:05.83000:02:05.840 you can see just kind of like three 00:02:07.71900:02:07.729 different tabs and here and a really 00:02:10.93000:02:10.940 thick so they're definitely able to 00:02:12.49000:02:12.500 handle the current and right now this is 00:02:16.00000:02:16.010 just paper oh here comes the beginning 00:02:18.04000:02:18.050 of it booth it's got like this dry 00:02:24.43000:02:24.440 carbon looks like a dry carbon just yeah 00:02:31.12000:02:31.130 this is like a feels like a paper but 00:02:35.59000:02:35.600 it's got this black dry carbon on it 00:02:37.54000:02:37.550 so definitely different it's dry it's 00:02:41.92000:02:41.930 definitely not wet like an electrolytic 00:02:46.74000:02:46.750 here's one of the tie-in spots and that 00:02:50.74000:02:50.750 is really thick and I guess I'm just 00:02:54.61000:02:54.620 black believe it or not this is actually 00:02:56.53000:02:56.540 getting a little cool to the touch 00:02:59.43000:02:59.440 definitely I clean my hands after this 00:03:01.24000:03:01.250 I'm not sure what's on it but come on 00:03:04.78000:03:04.790 short this is lithium now definitely not 00:03:08.62000:03:08.630 it ripped too easy like paper it's like 00:03:11.05000:03:11.060 a black paper or some sort I think it's 00:03:16.21000:03:16.220 a form of carbon that's been printed 00:03:18.10000:03:18.110 onto it but I'm not sure it definitely 00:03:24.16000:03:24.170 rips easily and it's definitely cool to 00:03:25.72000:03:25.730 the touch so I'm not sure what type of 00:03:27.28000:03:27.290 metal it is but this is definitely 00:03:29.28900:03:29.299 different never seen this inside of an 00:03:32.41000:03:32.420 electrolytic capacitor yeah it's 00:03:34.09000:03:34.100 definitely getting cool so it's reacting 00:03:37.00000:03:37.010 it almost like it's an endothermic 00:03:38.53000:03:38.540 because it's touching air now so I'm not 00:03:40.81000:03:40.820 sure but it coils for quite some time so 00:03:45.75900:03:45.769 the basic setup is like an electrolytic 00:03:49.21000:03:49.220 capacitor but instead of using two 00:03:50.86000:03:50.870 metals separated by a membrane this 00:03:54.25000:03:54.260 one's got paper for membrane but it's 00:03:57.09900:03:57.109 got this black stuff that's cool to the 00:03:58.93000:03:58.940 touch and you know they all get cancer 00:04:01.44900:04:01.459 from this so there you have it you have 00:04:04.27000:04:04.280 the regular electrolytic capacitor which 00:04:06.34000:04:06.350 I'm sure there's other videos on YouTube 00:04:08.17000:04:08.180 that show it's just two pieces of metal 00:04:11.03000:04:11.040 with a separator in and little 00:04:13.36900:04:13.379 connectors versus a super capacitor 00:04:16.87900:04:16.889 which has this black paper which I guess 00:04:19.84900:04:19.859 is carbon coded that doesn't come off on 00:04:21.77000:04:21.780 your hands and it's kind of endothermic 00:04:25.01000:04:25.020 it's a little cool to the touch not like 00:04:26.99000:04:27.000 frozen or anything like that but it's 00:04:29.06000:04:29.070 definitely cool to the touch and if we 00:04:31.82000:04:31.830 remember looking at the bars on it it 00:04:35.21000:04:35.220 has an awful lot of contact surface so 00:04:38.68900:04:38.699 that's how you get your high amperage 00:04:40.40000:04:40.410 from a super capacitor if you have any 00:04:44.45000:04:44.460 questions or comments go ahead and leave 00:04:46.18900:04:46.199 them below thanks
