find their respective resistance..and find the difference, it will be = 0.03 ohms.

oohk .. i hav a different method .. might get complicated but fairly accurate ..

first of all the resistors are all the same .. so v can assume a specific resistance for each one .. say 2 ohm ..

For circuit  1 ==> total resistance ..
1/2 + 1/2 + 1/2 = 3/2

so = 2/3 = 0.667 ohm..

For Circuit 2 ==> total res. ..
1/4 +  1/2  =  3/4  

so = 4/3  =  1.33 ohm ..

therefore it is clear tht circuit 2 double of 1 .. :)

Not really sure. A friend of mine mailed the photos to me. He said something like "Federal Physics."  Never heard of it from anyone before.....

where does it say each resistor is 2 ohms?arent we supposed to use the calculated value fram a(ii)

its not mentioned the resistors are of 2 ohms .. we can assume 2 ohms because they are the same ones being used

however u might use the readings given .. jus fo ur understanding i hav used 2 ohms ... DONT GET CONFUSED!!

I ASSUMED JUS FOR THE SIMPLE REASON because THEY R SIMILAR ;) .. ITS MENTIONED .. IF NOT NEVER ASSUME STUFF !!  :) :)
