1
00:00:00,990 --> 00:00:10,890
So before we start discussing our electric current is a voltage recharge and etc. We would like to identify
2
00:00:11,040 --> 00:00:14,380
something which is called the system of units.
3
00:00:14,580 --> 00:00:22,470
We all know that z lengths of something can be having a unit called meter OK.
4
00:00:22,530 --> 00:00:27,010
We measure zillions of something a by meter.
5
00:00:27,090 --> 00:00:30,670
We can say that we have a 1000 meter as a distance.
6
00:00:30,690 --> 00:00:39,960
We have a t shirt of for example 50 centimeter for example which is the unit of measurement.
7
00:00:40,020 --> 00:00:43,790
All of this are called unit of measurement.
8
00:00:44,010 --> 00:00:44,680
OK.
9
00:00:44,740 --> 00:00:54,030
Ze mass can be measured by KG zero time is measured by second all of these are called units of measurement.
10
00:00:54,030 --> 00:00:57,370
But here you will find something that lends.
11
00:00:57,540 --> 00:01:05,040
For example here in my own country we use km for measuring ze distance in other countries.
12
00:01:05,040 --> 00:01:13,910
They use mile as a unit of measurement and there are other units for measuring resilience.
13
00:01:14,010 --> 00:01:24,270
So in order to unify the unit of measurement they have met something called s all unit is the eye unit
14
00:01:24,420 --> 00:01:34,810
is an abbreviation for ze international system of units so instead of someone is measuring with a meter
15
00:01:35,130 --> 00:01:38,140
as a one measuring with mile for example.
16
00:01:38,200 --> 00:01:39,700
Also for the mass.
17
00:01:39,700 --> 00:01:42,950
Someone measuring in kg.
18
00:01:43,090 --> 00:01:45,110
Others measure inbound.
19
00:01:45,160 --> 00:01:48,100
All of these are different units of measurement.
20
00:01:48,100 --> 00:01:55,870
So in order to unify all of this unit they have made something called a small unit or ze international
21
00:01:55,870 --> 00:01:57,850
system of units.
22
00:01:57,850 --> 00:02:02,340
So for that is all units as islands is measured by meter.
23
00:02:02,800 --> 00:02:10,630
Ze mass is measured by kg and time by second is the electric current which you are going to discuss
24
00:02:10,690 --> 00:02:18,190
is measured then and there is a similar dynamic temperature is measured in Kelvin and of course other
25
00:02:18,190 --> 00:02:20,730
countries use sleaziest degree.
26
00:02:21,010 --> 00:02:31,980
But in order to unify the use kelvin ze luminous in Dynasty Candela Zi charge in Quantum and this are
27
00:02:32,020 --> 00:02:41,600
a unit of measurement and zero symbol when we are talking about less than metre we say ten and ze abbreviation
28
00:02:41,600 --> 00:02:49,410
or the simple M Zi KG cagey ze second S and pair a and so on.
29
00:02:49,550 --> 00:02:57,050
Now another thing about Ze system of units or is all unit or the international system of units you will
30
00:02:57,050 --> 00:03:00,280
find your something which is called the Z multiplier.
31
00:03:00,350 --> 00:03:13,100
So for example instead of saying I am having 1000 meter Let's type here as an example for this this
32
00:03:13,100 --> 00:03:13,860
one okay.
33
00:03:14,300 --> 00:03:16,910
So instead of saying 1000
34
00:03:20,640 --> 00:03:33,410
meter has a distance I can see 10 to ze power Siri which Siri here representing ze number of zeros.
35
00:03:33,720 --> 00:03:34,680
Okay meet.
36
00:03:35,410 --> 00:03:35,930
Okay.
37
00:03:36,310 --> 00:03:42,340
So this tempo three representing ze at 1000.
38
00:03:42,590 --> 00:03:43,140
Okay.
39
00:03:43,390 --> 00:03:47,340
So tempo 3 can be replaced by kilo.
40
00:03:48,030 --> 00:03:48,770
Okay.
41
00:03:48,820 --> 00:03:52,950
Which is having having a symbol called the K.
42
00:03:53,070 --> 00:04:02,780
So instead of writing tempo three M we can say k m okay which is a km.
43
00:04:03,300 --> 00:04:03,900
Okay.
44
00:04:03,910 --> 00:04:08,810
K here representing is the tempo 3 which representing is a 1000.
45
00:04:09,130 --> 00:04:18,370
So instead of writing all of this I can say K M which is K representing ze multiplier and M representing
46
00:04:18,400 --> 00:04:29,100
our unit so we have here Temple Street can be abbreviated by kilo Temple 6 by mega Temple Mount Ganga
47
00:04:29,540 --> 00:04:31,260
Temple 12th Terra.
48
00:04:31,380 --> 00:04:37,770
And of course we can decrease our numbers Temple negative to Santi then tampon active city merely and
49
00:04:37,770 --> 00:04:38,850
so on.
50
00:04:38,850 --> 00:04:51,200
So as an example for this if I having ten four negative six micro F which is a far out representing
51
00:04:51,210 --> 00:04:57,960
the unit of capacitance coalescence which we are going to discuss in the course m here is the micro
52
00:04:58,620 --> 00:05:01,880
which is the abbreviation for Temple negative 6.
53
00:05:01,980 --> 00:05:02,370
Okay.
54
00:05:02,760 --> 00:05:14,120
So we can say Micro Four out okay or we can say 10 power negative 6 four out.
55
00:05:14,510 --> 00:05:15,250
Okay.
56
00:05:15,400 --> 00:05:18,960
This one is equivalent to this one.
57
00:05:19,300 --> 00:05:26,170
Another thing if I would like to say one 1 million okay.
58
00:05:26,450 --> 00:05:28,660
Six zeros.
59
00:05:28,810 --> 00:05:31,690
One two three four five and six.
60
00:05:31,720 --> 00:05:34,890
So have your 1 million for example meet.
61
00:05:35,770 --> 00:05:36,420
Okay.
62
00:05:36,670 --> 00:05:44,860
So instead of saying one million meter we can say and instead of this we can replace ze million which
63
00:05:44,860 --> 00:05:48,410
is Tempel 6 by M which is ze make.
64
00:05:48,430 --> 00:05:49,900
So I can say mega
65
00:05:54,050 --> 00:06:02,280
mega metre means that we are talking about M then 4 6 which is representing one million meter.
66
00:06:02,600 --> 00:06:13,580
OK so that benefit of this is used to minimize the number or we can represent a larger number by a small
67
00:06:13,670 --> 00:06:14,740
symbols.
68
00:06:14,750 --> 00:06:23,390
So kilo can be represented by K mega M giga G and so on at Temple negative 2 which is the something
69
00:06:23,390 --> 00:06:30,980
meter for example which is seen then by an active city which is similarly M micro atom bomb negative
70
00:06:30,980 --> 00:06:31,330
6.
71
00:06:31,340 --> 00:06:32,660
And so on.
72
00:06:32,690 --> 00:06:41,420
Okay so this are as ze abbreviations which you will need to understand for yourself and this are ze
73
00:06:41,800 --> 00:06:46,130
as all units when we are talking about lands mass time and so on.
