The video was really helpful for my exam preparation. Thank you so much for your assistance once again!

[@abrahammathew3752]

Everthing you taught was great Sir! But, in 14:36, the circuit didn't work because the arrangement of the cells were wrong like + - - +, but it should come + - + -. Both the circuits were also closed. But other than that, everything was very clear!

[@rockwithparth222]

yeah even i thought of that

[@abrahammathew3752]

Sir was just going with the flow and forgot the concept of the arrangement of cells🤭

[@tanvigowda318]

No actually sir is right, they have asked there that why doesn’t the bulb go low in this circuit , that’s why they given that diagram where - and - are connected together , if u don’t understand see the video once again 😊

[@abrahammathew3752]

@@tanvigowda318 That is exactly the point, but Saurabh Sir didn't see that. Instead, he told that the reason the circuit didn't work was that it was open.

[@Kabeer78-v2j]

sir current is a controlable and convential energy which is used for our daily uses

[@Gaming_Beast321s]

16:00 Answer is wrong The correct answer is: as negative terminal is in contact with negative terminal the bulb isnt glowing The diagram was correct

Sir you are telling that why doesn't the bulb glow in this circuit and Sir you say that the switch is in the off position that why but Sir doesn't tell that the Battery are also not in correct position in 1 fig the Positive terminal is connected to positive terminal and negative terminal is connected. Negative terminad that is also a problem we have to connect positive to negative then only the bulb will glow and the Circuit is close🤗.

[@rajeshdeepak3614]

In the vid the teacher said st wrong at the time 15:47 The bulb doesn't glow coz of the wrong arrangement of cells, and not because the circuit was closed --- according to sir. It clearly shows the closed switch over there. Otherwise the vid was good.

Hi sir, you are an incredible teacher! Thank you for helping us. Anyway, the answer that you explained on 16:10 is wrong.. the answer should be that the negative terminals are connected to each other which is why the bulb isn’t glowing…. Please take into consideration… thank uou

5:15 flow of electicity is known as current

[@iovefiness3836]

Sir I have filament bulb at home.

[@a.d.ssyedabbas81]

Sir nowadays you are speaking more in Hindi And it's getting harder for other language students to understand

[@electricgaming9720]

1st question answer: current is the flow of charged particles (electrons) in wire. 2nd question answer : because the circuit is open and the electricity doesn't flow that's why the bulb is not glowing. 3rd question answer (oral): Depends on the device you are using .Just like when you use the heater the coil gets hot by conducting electricity and it feels hot ( because it has a heating element), but when you touch the bulb and you feel hot, it is because of the conduction of electricity and thus producing heat. And because of collision of charges with a atom when moving in a wire. 21:14 4th question (oral) : Incandescent bulbs are used old houses or for a decorstion for an occasion ,or for fancy lighting. 5th question: (imp) what is an incandescent bulb? : Incandescent bulb is a bulb which were used in houses in old time or are used in restaurants for fancy lighting,and are still being used old houses. it is made up of outer glass coating 2 filaments(supporters) and a tungsten rod in between. why tungsten? its is used because it has a very high melting point. 6th question answer: why we started using CFL and LED bulbs instead of using normal incandescent bulbs?: it is because filament bulb uses too much electricity much that 100 watts but does not give enough light and it produces heat so it is a waste of energy at tis point.We use CFL and LED bulbs because not only they are energy efficient but produces more light than incandescent bulb such at 8 watts 9 watts 10 watts . ( fun fact they do not even produce that much heat). 7th question answer : it is possible but in couple scenarios but in general no. But in general ther is a fuse wire which limits the electricity flown to the tungsten wire and thus does not make it melt or break. there are many questions but answering this much only because my hands are hurting like hell. But i hope this helps you. ;)

[@durgacharanpanda5213]

For your kindly information, the answer which you have given to the 2nd question is wrong, actually the current only flows when the cells are joined in series and when the negative terminal of one cell kept in contact with the positive terminal of other, but in that figure, the negative terminal of one cell kept in contact with the negative terminal of other cell, that's why the current will not flow through it and the circuit breaks. Therefore, the bulb will not glow.

The flow of electricity through a conductor such as metal wire is know as electric current

[@Nishita_meh]

The necessary items required to build a torch are wire, cell, and a bulb 𝐚𝐧𝐝 𝐚 𝐬𝐰𝐢𝐭𝐜𝐡 that lights when the circuit is complete. An electric cell is a source of electricity that is inserted in the torch. The electric cell is connected to the bulb of the torch through a wire.
