I don't know total resistance in parallel (1/R1)+(1/R2)+(1/R3)+(1/R4).

So, please give me an answer and explain in simple.

I'm not getting for the fact that only R2 is given and we're required to calculate total resistance.

1/1000+1/2000+1/3000+1/1000=0.00283.

1/0.00283=353.

1/0.00283=353.

Try to send current through one of the points from open circuit side and try to reduce it by parallel rule.

RT = 1/R1+1/R2+1/R3+1/R4........1/RN formula 1/1000, 1/2000, 1/3000, 1/1000.

RT = 5+2.5+1.66+5/5000 Lasavi.

= 14.16/5000 Moho.

= 5000/14.16 ohm.

Answer = 353 ohms.

RT = 5+2.5+1.66+5/5000 Lasavi.

= 14.16/5000 Moho.

= 5000/14.16 ohm.

Answer = 353 ohms.

Sorry @Ragavignesham I am unable to understand. Can you please explain in more words?

It is very simple ,

If we calulate like this,

Here,

R1=1k.

R2=2k.

R3=3k.

R4=1k.

If we do R1||R4 then simply 1k||1k=500 Ohms.

So final answer should be less than 500 ohms as there are R2 and R3 are there.

And in option there is only one option which is less than 500 Ohms.

So 353 is the answer.

Hello Friends.

There are three resistance values...say R1, R2, R3, R4.

First calculate R1||R2 = 2/3 = r1 then, r1||R3 = 6/11 = r2 then, r2||R4 = 0.3529K = 353 ohm.

Finally R1||R2||R3||R4 = 353 ohm.

1/Requ = 1/R1 + 1/R2 + 1/R3 = 1/1 + 1/2 + 1/3 + 1/1 = 17/6 kohm.

Requ = 6/17 Kohm.

Now convert 6/17 kohm into ohm so multiply with 1000(1kohm=1000ohm).

So 6/17*1000 = 352.94.

Requ = 6/17 Kohm.

Now convert 6/17 kohm into ohm so multiply with 1000(1kohm=1000ohm).

So 6/17*1000 = 352.94.
