The equivalent resistance between points A and B of the resistors shown in the figure is 27Ohms.
Find the value of resistance R.
Here is the diagram: http://session.masteringphysics.com/problemAsset/1122575/1/Walker.21.36.jpg
Rseries = R1+R2+R3...
The Attempt at a Solution
Not really sure where to even start, having a real hard time with equivalent resistance. If someone could point me in the right direction it would be greatly appreciated.
