1
00:00:01,439 --> 00:00:14,619
okay in the parallel connection we find that all these resistors are a little bit different since

2
00:00:14,619 --> 00:00:23,739
this one is orange orange brown right this one's red red brown so you put the values here

3
00:00:36,539 --> 00:00:49,229
so the first one is just like the one we saw before okay the second one i think is

4
00:00:50,670 --> 00:01:06,930
30 so the total resistance in this case we cannot measure it i mean we cannot add just like here

5
00:01:06,930 --> 00:01:36,930
since we are in series and in series we know that we have to use this equation to calculate it okay

6
00:01:36,930 --> 00:02:01,200
we're going to use the calculator directly we have this value okay if we

7
00:02:01,200 --> 00:02:12,240
want to change it to we have to press it two times okay to get this value like this so it's zero

8
00:02:12,240 --> 00:02:36,030
point zero zero seven five eight okay whatever and now if we have this we know we have to

9
00:02:36,030 --> 00:02:46,229
turn it upside down or pass this over here dividing past the resistance to this side

10
00:02:46,229 --> 00:02:54,969
multiplying right so we isolate the resistance and in the calculator we should just press

11
00:02:54,969 --> 00:03:07,490
this button so the resistance is 88

12
00:03:07,490 --> 00:03:26,830
okay and now we have to calculate these values since it's a parallel circuit we know the value

13
00:03:26,830 --> 00:03:40,669
of the voltage is the same which is three volts okay now in this case we know in series

14
00:03:40,669 --> 00:03:52,300
there is the the current that goes through two or three resistors that are in series

15
00:03:52,300 --> 00:04:08,389
is the same so we can say the total current equals i sub 1 equals i sub 2 equals i sub 3

16
00:04:08,389 --> 00:04:18,629
okay we write it there okay it's the same one the total it's the same okay so

17
00:04:18,629 --> 00:04:28,970
if this is 23 this one this one is 23 23 23 right in parallel in parallel we have to

18
00:04:28,970 --> 00:04:32,569
calculate the currents like this

19
00:04:32,569 --> 00:04:51,209
which is 3 divided by 150,000

20
00:04:51,209 --> 00:04:55,790
3 divided by 330

21
00:04:55,790 --> 00:05:30,829
ok, ok, we will calculate this and this

22
00:05:30,829 --> 00:05:33,209
and just write it there
