00:00Welcome all of you to this channel with one more educational video from a new educational video
00:11So, let's go to our note pad and learn something new today
00:20Four students set up the circuit
00:22Four students experimented with Ohm's law
00:27and connected the circuit like this
00:30First student connected like this, second student connected like this, third student connected like this and fourth student connected like this
00:39In this we have to tell which of the following option is correct
00:44or which child has connected the wires correctly
00:50First, let's look at the thick ones
00:52As we look at each one
00:54We can also consider this to be correct for a while
00:56But we can't consider this to be correct because he has connected all of them in series
01:00In this, they don't connect in series
01:02This is wrong
01:03Now, if we look at this
01:05What has he done?
01:07This is positive and this is negative
01:09This is correct, but the current is flowing from here
01:12So, this is negative and this is negative
01:14Whereas, the current should come from here to here
01:17So, this will also be wrong in this
01:20Now, we come to this
01:22What is this?
01:24The child has connected it correctly
01:26But what has he done?
01:28He had to connect the voltmeter in parallel order
01:30He has connected the ampere meter in parallel order
01:34So, what is this?
01:50Let's write it like this
01:52First, let's erase this
02:05Hindi medium
02:07We will write this in Hindi language
02:09Language doesn't make much difference
02:12We also studied in Hindi medium
02:15The main thing is that
02:17Your concept should be clear
02:22Parallel combination
02:24Correct circuit
02:26Circuit setup
02:36Observe the following incomplete ray diagram of an object
02:44Where image A'B' is formed after refraction from a convex lens
02:55You can see that this image is upside down from the convex lens
03:00First, we have to complete this figure
03:05As we all know
03:07There are some rules of ray
03:11Whichever ray comes from the principal axis
03:14This state comes out
03:17And from its end point
03:20If we remove one ray from here
03:24Then its position comes here automatically
03:28Now, how does this ray go?
03:31Because the figure is on the left side
03:35So, we have to move from right to left
03:38Because we have been given in this way
03:40So, we pass one ray from here
03:45Obviously, it will go here
03:49Like this
03:51It came here
03:53Now, at this point
03:56There is an object
03:58Image is A'B'
04:02So, we show its object from A to B
04:06This is our object
04:10Here, my space is less
04:13You can understand it like this
04:16Still, the figure is clear
04:19I write this
04:21A'B'
04:23So, we show it from A to B
04:25A
04:27AB
04:29This is our object
04:31This is AB
04:33Now, one ray will go straight from here
04:37From its main point
04:40And the ray which goes straight
04:43From that lens
04:46It will turn towards the focus from here
04:50So, it will come out like this
04:54Like this, our diagram is complete
04:59This is my picture
05:02You can manage it
05:04Still, the correct diagram is
05:07It will be complete like this
05:09One ray goes straight
05:11You have to make it straight
05:13Because it is colliding with the lens
05:15After colliding, the ray will turn
05:17Where will it turn?
05:18It will turn towards the focus
05:20One ray will go from here
05:22It doesn't have to turn anywhere
05:24It will go straight
05:26The intersection of these two points
05:29It will intersect at some point
05:32So, it will be the same point
05:34Where the image is being formed
05:37We have been asked two questions
05:40We were also asked this question in Viva
05:43In Physics
05:45Maybe, such questions are asked
05:49What is the position in this?
05:51The position of
05:53The position of object A would have been
05:57Where would be the position of A?
06:00Behind
06:02Behind 2F
06:04We will write it behind 2F
06:07Behind 2F1
06:13Behind 2F1
06:16From 2F1
06:19If we want to write in Hindi
06:22From 2F1
06:25Here is the right
06:28Here is the left side
06:30Left side
06:33Left
06:35Side
06:37Side
06:39Now
06:41Size of
06:43Size of the object
06:46Would have been size of
06:48As you can see
06:50The size of the image is very small
06:53And the size of the object is big
06:56Size of the object
06:59Would have been
07:01Bigger than the size of the image
07:06Bigger than
07:08The size of the object
07:10Would have been bigger than the size of the image
07:14If you had asked the question in Hindi
07:17Bigger than
07:19Bigger than
07:21This is a small question
07:23And that's the end of this episode
07:26This episode ends here
