Homework Statement


Multiple-choice physics problem showing a resistor network between nodes A and B, with resistors labelled 10 ohm, 20 ohm, 10 ohm and 10 ohm, and answer options (A) 10 ohm to (E) 50 ohm.

The Attempt at a Solution


Hand-drawn circuit schematic with terminals A and B and labelled nodes C, D, E and F, containing several resistors connected between them.


I tried to break it down to:

Hand-drawn circuit schematic with nodes labeled A, F, D, C, B and E; resistors sit between A and F, between D and C, and in branches from F, D and C down to node E, with a wire from A to B.


But apparently it is incorrect, can someone tell me the correct configuration? And explain too! Thanks :)

Oh nevermind just realized this is is a wheatstone bridge, silly me

LOL. How about an unambiguous hint? Like using KCL equations to solve it. There may be a trick that you can use, but if you don't see the trick pretty quickly, just doing the KCL equations and solving should get you the answer. And for a circuit this simple, The KCL equations are fairly easy.

Oh, never mind then. :smile:
 
Helpers are not allowed to directly provide solutions to homework questions. They can only offer hints, suggestions, or point out mistakes or correctly done parts in your work.

What makes you say that your rearrangement is wrong? The only problem I can see would be if you incorrectly locate the 20 Ω resistor on the figure (you didn't label any of the the resistors, so I can't be 100% sure that you've got that right).

Edit: Just saw the OP's latest post, correctly identifying the circuit configuration. So never mind :smile:
