What will be A and D the equivalent resistance and also between between C & B ?
Answers
Answer:
We know that to find equivalent resistance in series we have to simply add both the resistance
So Req(PQS)=20Ω
Req(PQS)=20Ω
And Req(PRS)=20Ω
Req(PRS)=20Ω
Now the figure becomes,
Now both the 20Ω20Ω resistance are in parallel connection with each other, so we know that the equivalent resistance for parallel connection is by
1Req=1R1+1R21Req=1R1+1R2
So Req=R1×R2R1+R2Req=R1×R2R1+R2
Now putting the values, we get,
Req=20×2020+20Req=20×2020+20
Req=10ΩReq=10Ω
Now all the resistance between the points A to D becomes in series,
Hence, we can add all of them and get the final equivalent resistance.
R=10+10+10R=10+10+10
R=30ΩR=30Ω
Hence, we can conclude that option (C) R=30ΩR=30Ω is the correct answer
