PG team please add this video in playlist of capacitance, its difficult to find this video, please do it ASAP

[@nehaprasad7953]

sir please upload the video in which we can find c equivalent of complicated circuits that is using 4 types of symmetrical methods ......that cube and star problems can be solved easily ......as in advance illustration u have done it by nodal analysis

Why is the charge across 5F capacitor is 5(x-50), shouldn't be it 5(50-x)?

[@physicsgalaxyworld]

+Mukul Jindal No... we are using total charge on the plates connected to x to be zero... so this is the charge on that plate of capacitor which connected to x.... it is -5(50-x)

[@hetanthakkar4532]

"sum of charges is 0 as charges cnt jump from plates",can u please ellaborate i didnt get it completely

[@ashwathkrishna3941]

charges are static! meaning there can only be induced charges of the same magnitude and since this is *electrostatics* and not current..charges arent travelling...hence the isolated system will have a net charge of 0

Sir please add this video in the capacitor playlist

they still didn't add

Thank U sir

Sir hats off thank u so much

[@jainamsavla6253]

Sir while solving example of the nodal analysis circuit the value of x is wrong it is found to be 10/3 instead of 50/3. Everyone can cross-check my answer by solving this sum

[@sahejsodhi5909]

It's 50/3 only

[@jainamsavla6253]

@@sahejsodhi5909 yes thank u I got it I made a mistake while solving

[@divyanshisingh8071]

50 /3 is correct ...

Thank you so much sir:)

[@aniketsinha101]

Sir how will we know that potential at the node which we assumed to be x will be higher or lower wrt to voltage V

[@ashwathkrishna3941]

see which terminal of the battery its connected to!

[@adarshkundu5995]

sir can we get your notes to refer from......please give us a pdf or a site to download it from a site

[@ihatesnakeu4923]

Sir can you solve the example 2.18 in the physics galaxy book of chapter capacitance pls

[@mohitsinghrathore2657]

the potential difference is x-50 why not 50-x

[@physicsgalaxyworld]

Because we are finding the charge on plate connected to x... on the other plate charge will be opposite of this...

[@prateekchauhan6376]

Physics Galaxy ok.. means it is done because the two capacitors in parallel have X connected with left plate .. but the one with 5 uF has X connected with right plate

[@shaurya_aggarwal_G]

@@physicsgalaxyworld 🤯🔥👍🙏

[@divyar8402]

respected sir, why is charge at node 0 ..plz could you explain

[@divyar8402]

also sir isn't the potential diff 50-x and not x-50

[@divyar8402]

like why are we talking the potential difference as( lower -higher) potential for circuit before node and higher -ower potential for circuit after node

[@divyar8402]

by making it x-50 we'll make it negative and as the lowest potential in the circuit is 0 The other potentials in the circuit should be
positive

[@physicsgalaxyworld]

the node is connected to only three plates of capacitors which were uncharged initially...

[@physicsgalaxyworld]

Yes you are right thats why this method works... and you don't need to think much before writing the equation...

[@arohibisht4625]

Sir plzz tell how to determine the potential difference across two given ends in the circuit

[@physicsgalaxyworld]

Use either junction rule or KVL...

[@arohibisht4625]

sir can we use nodal analysis method to determine the PD across two points

[@physicsgalaxyworld]

Yes you can do that...

[@anuragporwal4664]

Can we write equation even if capacitor is charged initially.

[@hossainboard86]

Yes

Yes bro i am having the same problem ...can you guide me ...

[@amaanali7036]

Sir why do we have taken x-50 can't we take 50-x

[@physicsgalaxyworld]

To save time in thinking we consider and apply KVL as sum of all outgoing currents from junction is zero... thats why we took x-50...

[@kumarsambhav6844]

PG Team change the title of the video its not "model" its "Nodal" Analysis

[@physicsgalaxyworld]

Thanks... it was a typing error... corrected it...

[@prateekchauhan6376]

its still incorrect.. you have written MODAL
