hello again I'm going to explain the last thing of the of the of the unit
00:00:00
yeah that is how to calculate total capacity of a circuit okay it's it's not
00:00:07
difficult this this part okay so let's go directly to an example so for instance
00:00:22
we have this case we have two capacitors yeah in this way this way think thinking
00:00:36
resistances and when we studied this before we said that this is a parallel
00:00:53
or serious serious circuit yes it's a parallel circuit yeah yeah so in using
00:01:03
resistances a do you remember the formula yeah
00:01:19
over r1 plus 1 over r2 plus blah blah blah yeah nothing else yeah but using
00:01:33
capacitors this goes in a different way but not in a in a in a difficult way
00:01:45
because it's it works in the opposite way so we see a parallel circuit think
00:01:53
in serious circuit using resistances so for instance if you have here 1 milli
00:02:03
farad and here 2 milli farad the total capacity of the circuit is total capacity
00:02:10
is let me call this c1 and this c2 yeah so the total capacity would be 1 milli
00:02:26
farad plus 2 milli farads 3 milli farads and that's all okay and if we have more
00:02:39
than two condensers capacitors connected like this okay like this we just need to
00:02:55
add them okay the total capacity would be the summatory of each one okay do you understand
00:03:16
this summatory if you don't understand forget this and think just in um and adding one by
00:03:28
one okay okay so new one new one no I don't want yeah so it's a parallel what happens if we have
00:03:38
this example one and another capacitor imagine two milli farads and four milli farad are they
00:03:49
in parallel or is a serious secret yes serious secret okay serious secret so think in the opposite
00:04:08
way when it's not like resistances now the total value is using the formula yeah but but we are
00:04:22
going to use the we are going to be cheaters yeah so we are going to we are going to use the trick
00:04:37
the trick remember total capacity is the division of what here we multiply the values and here we
00:04:45
add the values it only function with two two capacitors if we have three we would need to add
00:04:56
this and this and then this this and this now we need to do this formula the formula with two and
00:05:07
then the result with the other one okay okay so we have two if we have the same units we can forget
00:05:19
the units for a while and we type the units at the end to multiply by four here two four okay so this
00:05:29
is 8 over 6 we can do this for this its value is 1.33333 as I said to decimals milli farads
00:05:43
okay because we have milli farads here in both capacitors okay I'm not going to to put more than
00:06:07
that so maybe three but not more than three imagine that here we have another capacitor of
00:06:22
six milli farads so we would need to do this again but instead of two and four this value
00:06:29
would be 1.33 and instead of four six yeah so just to finish one the last one and a mixed
00:06:39
circuit no I don't want to see so something like that something like that okay it's a mixed circuit
00:06:50
here we have two capacitors connected serially and together parallel okay so how do we solve this
00:07:13
so path by path so first of all these two these two are connected serially sorry I forgot to type
00:07:30
the value so maybe four milli farads four milli farads 10 9 9 8 8 8 milli farads and here for
00:07:40
okay so first of all this we can call this one two and three okay so consider one two is four
00:08:01
multiplied by 8 here 4 plus 8 so this is 32 over 12 we can divide this by 4 for 8 over 3 and it is
00:08:21
2.67 67 watt milli farads okay always the same unit so we can type here milli farads okay and
00:08:44
then this this condenser that is the same as this two it's connected parallel in parallel with the
00:09:00
third one okay so total resistance is as we said that is in parallel we just need to add both c1 2
00:09:13
plus c3 so if we are 2.67 and 4 milli farads we have 667 okay so just to finish and what I remember
00:09:26
from now what I want you to know for the we are going to have an exam I'm going to tell you it in
00:09:52
the post okay what I want you to know and what I want you to know to the exam and the exam will
00:10:00
consist in a form in a form in Google okay and resistances for instance if I tell you we have a
00:10:12
resistance with this next bunch orange brown blah blah blah tell me the value of the resistance
00:10:29
symbols symbols of and diodes capacitors and resistances you know
00:10:36
and potentiometer I told you also and exercises with diodes which
00:10:50
which lamp lamps and this total total capacity more or less this is the and then I'm not going
00:11:11
you to to memorize anything because you are going to you can check all the information in your notes
00:11:39
it doesn't matter okay so that's all that's all okay see you stay at home see you ciao
