Household circuit || class 12th physics activity no 06 #household @a2zpractical991

So, hey guys, and welcome to my channel. Friends, myself Chetan Shukla and you are watching ATJ Practicals Friends, today's experiment is basically an activity. and that is basically a household circuit and the work of that household circuit is basically done in our homes and this household circuit was made in parallel and why it was made, all these things We are going to see through that circuit. Friends, this is the household circuit. which we are going to study And this is a very simple circuit. I'll tell you in a simple way The video is a bit long, but if you understand it then in your exam No matter what activity you are given, you can achieve good grades. Do not skip the video at all Friends, you support me support this channel because One of your subscribers is very important to me. if you support every single person on this channel Then I will feel very good. Let me begin the study of household circuits. and how to do it What all things are involved in it? I am going to tell you all these things You support me There are all practicals related to 11th and 12th. Go take a look at it. If you like it, then share it with your friends Today's Class 12 topic is study of household circuit In this, we have to learn how to connect all appliances in our house in a circuit so First of all, we will understand through these devices Everything is internally connected. You can see First of all the power supply is here household circuit in this activity We are going to learn. how to connect all appliances in our house How to supply power to all appliances We are going to understand this circuit. and we have this device First of all, what is our aim? our aim is to design, build, and demonstrate a simple household electric circuit See, this is in miniature form. means The circuit of our house is very complex. Here, we are going to take a big idea how to Connect our circuit. all devices In the apparatus, there is an on-off switch. 3-pin socket, flexible connecting wires bulb fuse, power supply, etc. This is Fuse. This is an indicator. And this is the AC main supply. In the main supply, we have to take care of two wires One is the phase wire. and the other is the neutral wire in circuit, phase wire normally gives 230 RMS voltage so we have to understand this connected wire is live wire in which, first of all We connect with fuse What is the reason? all devices in our circuit are connected to work on a voltage if we exceed that voltage The device can be damaged. That's why we connect first. because in our circuit We don't want any damage. So what is this fuse? whenever More voltage is applied. So what happens? This wire melts. Its melting point is very low. and when it melts Our circuit breaks so all our devices are saved before any problem occurs So this is the reason. for connecting Next is indicator in circuit whether voltage is applied or not Is current flowing or not? Next is socket You can see from the diagram This is our socket. this live wire has 3 terminals S1, S2, S3 is shown to the switch These are our switches. 1st, 2nd, 3rd 3 terminals of live wire And this is the neutral wire. See Live wire is 230 RMS. The neutral wire is 0 RMS. and to operate any device a potential difference is required We call it voltage. so This is 230 RMS and this is 0 RMS. when both are connected Current begins to flow from the device Actually, the device receives energy. so This is natural wire. We call it the neutral wire. Three terminals are removed. and connected to the switch in one switch There are 2 terminals. One is live and the other is neutral. and B1, B2, B3 You can see This is B1 and this is B2 and this is B3 The problem is We have taken only one bulb. All three are the same. Nothing is different. That's it. We're just checking. whether it is working or not We will test all three at different times. not at the same time Let's see. This is a circuit breaker. Let's supply power and see what happens Let's see how it works. as soon as we supplied power You can see The fuse started burning. It indicates that current is flowing. from the circuit now first bulb We will turn it on. and check whether it is working or not as soon as we turn it on You can see Current is flowing from the circuit. That's it. we learned how to Connect our devices. but The question is Why did we connect the device in this way? You can see This is live And this is the neutral wire. Why did we connect the terminal? between these two this type of connection is called a parallel connection The circuit is connected in parallel. What is the reason? the main reason is fuse safety of our devices OK How it protects our devices actually when we connect things in parallel all devices work independently whenever we connect our devices in parallel even if one device is damaged Other devices are working. two basic things we learned in this Chinatown First is fuse and the second is a parallel connection The fuse is for safety. so that our devices are secure And this is a parallel connection. so that our circuit does not break because suppose if our circuit breaks then instead of one device All devices will break. which no one will want This is the reason for the parallel connection. in series All devices are connected. where one device is damaged The entire circuit breaks. and all devices stop working now in this circuit diagram and in our activity What is the difference? in this circuit You can see E is shown What is this? This is earthing. means You can see There is no earthing. This is made for our experiment. the main purpose of making this device to do an activity to understand things but in our house Safety is our priority. earthing keeps our electronic devices and the entire circuit safe Earth is the biggest source in physics we always consider potential of Earth as zero because the purpose of earthing is not in this purpose is when we do wiring in our house we secure all appliances and in this There is no such thing. so friends You saw this activity You will like it. I have explained it. Thank you for watching This video and please subscribe A to Z practical Thank you.
