A good food for thought would be "can I consider an open switch as a capacitor?" If no, why not? If yes, then why don't we do the same analysis with it?" Also, since current flows with in a capacitive circuit, we have current flowing in 'open circuit'. Then why do we say we need a 'closed circuit'?
• A closed circuit is defined in terms of FLOW OF CURRENT ! and in capacitive circuit the current is not ZERO ! Hence the current is flowing so even if there is a break in connection of wires ! we would still identify the circuit as CLOSED CIRCUIT! An open circuit is the circuit in which no current flows whereas this circuit is just a circuit with a space between it (capacitor) NOT OPEN • And YES you can consider a OPEN SWITCH to be a CAPACITOR but the capacitance will be extremely LOW ! As it has its area in mm^2
Reminds me of my Math Teacher who taught us on the floor with multicolored chalks , and because of him I am till here . I am very thankful to my teacher 👍
You are genius sir....😁.I'm doing my btech from electrical and you easily clear all the basics and fundamental question arising on my minds .hats off to you sir🙂
Thankyou So much Sir .., not only for this only solution and but also for all your contribution towards physics . whenever any doubt comes in our mind the only name come's to every student is yours....
My doubt is :- We know that lambda(λ) is inversely proportional to refractive index(n) ie- λ ∝ 1/n so, now when we pass a light wavelength of 600-700nm that is a red light through a denser medium of very high refractive index then we should see a change in colour but when i tried it out then there was no change in the colour why is it so. I also tried searching it on google but found images which completely contradicts the relation between lambda and refractive index. (image)
Here when the human has passed a beam of green light through a bottle of oil then the colour has changed from green to red this means that refractive index is directly proportional to lambda as a light of lower wavelength has change to light of higher wavelength which is not true. I have been working on the problem from the last two weeks . I would admire you if you would clarify my doubt on board . thank you sir

Hi sir , myself himangshu saikia from class 10, My question is that , we all know the famous einstein's eq. e=mc² , where energy is equals to mass of an object , times the square of the speed of light . But as we know that the light photons are massless , so is it not violating this famous eq. in this case ? ( As we know that light photons also possess energy ) Plz clear this doubt 🙏
Sir, if flowing current have some magnetism then wire in which current is flowing why it don't attract metallic things. Please sir answer this still you think that this is a fool's question🙋
@H C VERMA Sir🙏🏻 I 'm in 9th Standard and i have a doubt can you please help me to clear this *DOUBT :-* If we take an example of pencil and the earth since the earth is attracting a pencil with some force and according to Newton's third law of motion here also the pencil will also attract the earth with same force but since the mass of earth is larger than that of pencil that's why the pencil gets attracted towards Earth and falls on it. On the other hand.. *We know that Earth attracts moon and by the Newton's third law of motion the moon also attracts Earth since the mass of earth is greater than the moon then why the moon does not get attracted towards Earth and falls on earth's surface?*
Due to its circular motion.......bro....as you're in class 9 th......so,i think you don't know about...the forces acting on body in circular motion........and how these bodies, where balance there........ Actually there's is strong force equilibrium between gravitational pull and centrifugal forces
@Pranav, the actual answer is an interplay between the type of force that gravity is, and conservation of angular momentum. Gravity is a conservative force which acts centrally. Consider Earth as origin, then there is no torque on moon due to gravity of earth, therefore according to conservation of angular momentum, there is no change in angular momentum of the moon, so it continues to rotate around the Earth. Had it been not rotating to begin with, i.e. since the time of it's creation, it would have fallen on the Earth. So in short, it could be said that it's not falling on Earth, since it began rotating when it was born and since nothing is stopping it from doing so, it will continue to rotate around the Earth. @ultimate racer: The sentence of yours: "there's is strong force equilibrium between gravitational pull and centrifugal forces" is not right. Moon is in an elliptical orbit around the Earth. That means that every moment it's direction/velocity is changing. This means that there is net force on moon which is causing change in it's direction/velocity. Force due to gravity is the centripetal acceleration, and this centripetal acceleration causes the moon to change its direction/velocity every moment while it is orbiting around the Earth. But for the sake of argument let's say that your statement is right, then there is no net force on the moon, therefore it should move in straight line, which it doesn't. If you liked my answer you might want to take a look at videos of my channel where I make physics related videos: www.youtube.com/@thephysicstrain
Sir I have some questions.. Question 1- In case of an open circuit how the emf induced across its ends is related to the magnetic flux change? Question 2- How is the damping force produced by the Eddy currents?
2) due to the internal resistance of the conductive material, the eddy currents will be dissipated into heat and the force will die out. As the eddy currents are dissipated, energy is removed from the system, thus producing a damping effect.
Answer -1 this will same as in case of closed circuit.....the Lenz law is equally applicable there Answer -2 ,this is a practical phenomenon, needs higher mathematics for understanding
@@punitasingh6659 you're asking about...how the emf is associated through magnetic field in open circuit.........so,the basically Lenz law..is also applicable there........more accurately...there is stoudla theorem.....which relates these two quantities for open circuit (but this THEORY generally discuss in PG courses.....i studied this theorem,when I was persuing my MSC).....
