    Can we all agree that this is one of the greatest videos on TH-cam? Honestly sir, you deserve a lot of respect because you teach with so much passion and love for the subject and it truly shows in the final product. A well explained video on a somewhat complicated topic. Well Done!

    Thank you sir❤️❤️
    Being a physics lover it is painful that every damn video on this concept on TH-cam explains how to solve the problem... Nobody cares what is actually happening in there.

    Thank you very much! I never really understood it in class (probably didn't pay enough attention, but it was overly complicated). Now, years later, I felt like looking it up again. Found your video and it really is as simple as that. Great explanation! Thanks

    Einstein said “If you can’t explain it to a 6 year old, you don’t understand it well enough yourself”. I would like to thank you for making me feel like a 6 year old again and taking the time to produce these videos.
    A big thank you.

    Wow, just wow. This is the most elegant explaination of wheatstone bridge ever. Thanks a lot man.

  • @dhruvgupta18
    @dhruvgupta18 ปีที่แล้ว +7

    what happens if the bridge is not balanced? ie. if the resistors are not in the same ratio...

    • @AmeyKalkotwarr

      Then there are certain cases like delta to star and star to delta conversion of circuits which can make it easier.

  • @Pricaliemily
    @Pricaliemily 3 ปีที่แล้ว +6

    This is a great video! I've read a few articles on Wheatstone bridge, they either do not give specific advantage of wheatston bridge or jump straight into Kirchhoff's law, which was confusing. This one solve all my problems.

  • @sabnamxettri4203
    @sabnamxettri4203 2 ปีที่แล้ว +7

    Not only this video
    Every videos of this channel provides conceptual knowledge and most important the teacher who explains is insane ...
    Thousands of lectures are there in you tube but you find here different
    You gotta feel the problem and realised how the college's teachers taught us such a easy topic in difficult ways...
    This channel should be protected 🙌

  • @sundararajankavinth
    @sundararajankavinth 3 ปีที่แล้ว +5

    I was actually confused. But once I watched this Everything was crystal clear. All other videos which I found were mainly focusing on Shortcut methods and problem solving. But this video nicely explained the theory well. Thanks a lot.

  • @ericksonengineering7011
    @ericksonengineering7011 2 ปีที่แล้ว +1

    Great video. But... you don't show how to solve the general case of an un-balanced bridge. That's the fun part, since it's pretty easy. Convert each side of the bridge (top and bottom 2 resistors) into a Thevenin equivalent, then it's just 2 voltage sources and 3 resistors in series. If you don't know how to do a Thevenin equivalent, look it up. It's a simple and very powerful circuit analysis technique that reduces ugly messy circuits into simple ones.
    Maybe your next video?

  • @goldenboy7697
    @goldenboy7697 3 ปีที่แล้ว +4

    Im a bit confused on the potential difference part because you can connect a wire but current is still flowing through the wire even though it has the same voltage or no potential difference

    • @Aman-yt5qk
      @Aman-yt5qk 2 ปีที่แล้ว

      man, i have the same doubt ⚡

    • @sehrishsofi7556
      @sehrishsofi7556 2 ปีที่แล้ว +1

      Current always flows from high to low potential.But when there is no potential difference it wouldn't flow at all.Take the analogy of two water tanks separated by a pipe when the water level is same in both the tanks,water wouldn't flow.Hope it helps.

    @sajidshahzaddurrani831 3 ปีที่แล้ว +2

    If I= same then how V∝R
    Because R is a constant.
    5:56
    Or does this mean that if we increase the voltage resistance will also be increased according. Or if we increase the resistance voltage will be increased.

    • @samsung-vq5rs
      @samsung-vq5rs 3 ปีที่แล้ว

      Both are ryt r is constant but if you replace r=5 to r=10 there is greater potential drop that's what he ment

    • @ycombinator765
      @ycombinator765 3 ปีที่แล้ว

      he is taking 'I' constant there, so it is resonable to think of Voltage varrying _in proportion_ to the Resistance.

  • @allthingsthataregood
    @allthingsthataregood 8 หลายเดือนก่อน

    how does same ratio give you same voltage? shouldn't it give you the same ratios of voltage? if the current in the upper wire experiences a 5 V drop and the one below experiences a 1 V drop, the currents resulting from them would be DIFFERENT!
