Homework is a SHORT. 0 ohms resistance. All resistors I believe are in parallel. Excellent videos, sir.

[@nayankarmakarofficial6294]

Wonderful trick to understand any ckt series or parallel....thank u

Thank you very much sir i love your the way of teaching keep it up 😍🥰

thank u sir.....just awesome

[@meemanshasoni4026]

Where can i check the hw problem solution

[@divyanshudeepak7495]

sir answer of home work question is 0 ohm. (beacuse current is having a clear path from point a ti point b).

[@AbC-bj3gs]

best best neso academy is best

[@roneiroger759]

Appreciate you sir for your work. But can you please provide us the solutions for the homeworks in the coming videos or else in the comments? It will be helpful.

Awesome teaching Sir!...Eagerly waiting for all the videos to come up. Please complete quickly.

Such a beautiful explanation...btw I have exam today 😂❤

[@kavyaachari92]

Since it is short circuit Req = 0 ohm. Can u plz confirm whether the answer is valid or not?

[@Kaspersky01]

It is valid

[@harshithsuda2899]

Thank you sir. I have finally understood the concept after so long.

[@Amreshcreations_.1703]

Thanks you sir

[@maganuriyev5005]

0 ohm, i think because Va is equal to Vb, terminals a and b are connected with the single empty wire.

[@syedmuhammadtaqishah2634]

Love you sir

[@yaazhinisenthilkumar6392]

HW qn ans: 20 ohms is it correct sir?

[@muhammadnouman3687]

Thanks@✌✌

[@subratdas8164]

a and b have same potential , means a and b are short circuited . so resistance in short circuited is always zero .

[@hyper69X]

Thanks

[@amansajwan6411]

Please explain h. W problem

[@abdessamedhazem3075]

the equivalent resistance is 5 Ohms Va = Vb (Short circuit) so all the resistances are in parallel

[@parthahluwalia6018]

Homework: 0 ohm

[@jallakaveri4405]

sir i got 22.5ohm as an equivalent resistance is it correct? pls reply sir and also tell correct answer..

[@stamu40]

I get the same answer

[@nirmala.3199]

It's 5

[@FreeFireGaming-vu6nc]

​@@nirmala.3199 Not it can't be 5 it has to be zero because as you first calculate parallel combination of central junction of resistors it will be 5 ohms but there is still a wire of zero ohm(wires are ideally considered to have no resistance) which is in parallel with 5 ohm equivalent and then when we calaculate 5 ohm parallel to zero ohm answer will be zero ohm.

If all resistors are connected in the middle, the answer is 6 ohm. Is it true?

[@Parth_Hansa_Tanna]

Sir homework problem ka solution bhi bhej do plz

[@sandeeptiwari3655]

I got va= vb........so resistance is zero ohm.....short circuited .....am I right??

[@shrishaildolle5642]

yes

[@suryaprakashiitbhu191]

Homework: As clearly we can see Va is equal to Vb (Va=Vb=V) so there is no potential difference and as there is no potential difference, current will not flow, but If we are concerned to find the equivalent resistance then all the resistors will be in parallel and answer will be 5 ohm

[@qemmm23]

Easy(3sec) Rab=10+((6//4//12)+1)//2))=10+(3//2)=10+6/5=11.2 ohm Thanks 😊

[@mitrasen2295]

Zero ohm sort circuit current will follow easier path

[@radhikaradhika9085]

Ans might be 5 ohms because potential difference at all nodes are equal so all nodes are connected in parallel.

[@nainarsuthan4344]

65.45 is correct or wrong?

The answer for homework question is 0ohm as the circuit is short-circuited with wires in the farther most loop. I have verified it using mutlisim software also.

5ohms.Sir,please upload answers

[@girishgautam5838]

[@TeluguWebTV1]

Ans: 0

[@physicsgraduate5718]

Net resistance = 5 ohm

[@Kaspersky01]

But the thing is a point wire directly connects to the b point wire making it a short circuit. So the electricity will pass directly a to b without the resistances.

[@ankitg2023]

HW ... parallel btw 4 parallels and a short circuit .. so Req = 0 x R para / 0 + R para = 0

[@ElectroMart90]

0 Ohm as a is directly short to terminal b.

[@user-rb3ok4gr7x]

All resisters in parallel but because of short circuit resister =0

[@crackbanking]

R=0,since a &b are short ckted

[@sakshidubey8101]

Sir but I didn't understand the last part

[@josea.r.avelino181]

homework: "a" and "b" are short-circuited

[@wilbowednesday1417]

All resistances are connected in parallel as they share the shame potenial. Equivalent resistance = 5 Ohms.

[@wilbowednesday1417]

5 Ohms in parallel with 0 Ohm = 0... hence 0 Ohm equivalent

[@josea.r.avelino181]

Va=Vb
