[@jackwilliam2226]

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

[@kavyaachari92]

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

[@Kaspersky01]

It is valid

[@divyanshudeepak7495]

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

[@vickyroy3595]

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

[@moazelsawaf2000]

Thanks a lot sir

[@Mehraj_IITKGP]

point a and b are at same potential, so equivalent resistance is 0

[@yaminisaraswathi2222]

[@yaazhinisenthilkumar6392]

HW qn ans: 20 ohms
is it correct sir?

[@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.

[@abdessamedhazem3075]

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

[@nayankarmakarofficial6294]

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

[@subratdas8164]

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

[@parthahluwalia6018]

Homework: 0 ohm

[@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

[@harshithsuda2899]

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

[@radhikaradhika9085]

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

[@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.

[@sakumieika]

weh..

best best neso academy is best

[@maganuriyev5005]

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

[@qemmm11]

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

yes

[@mathematicsphobia5495]

[@hkh1191]

its 0 ohm , because there is a clear path out of the resistance

What does clear path out of resistance mean?

#nesoacademy 22.5 is my answer

[@amansajwan6411]

Please explain h. W problem

[@meemanshasoni4026]

Where can i check the hw problem solution

[@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.

[@nainarsuthan4344]

65.45 is correct or wrong?

Ans is 20/3 as all of them are in parallel combination

[@ankitg2023]

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

[@sainalla5959]

All ends of resistors connected at same potential

[@ElectroMart90]

0 Ohm as a is directly short to terminal b.

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.

0 ohm Short circuit

[@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
