Homework Equations
V=IR
R=R1+R2 in series
R=1/((1/R1)+(1/R2))
All Resistors are 100 ohms
The Attempt at a Solution
I know that if one of the branches wern't there that it is a simple case of a paralell circuit and so the resistance is 1/R = 1/100 +1/100 = 1/50 therefore R across AO would e 50 ohms however I dont know what to do when the second branch is to be included.
Also sorry about the diagram i wasn't sure how to draw it the spaces just dissapeared, the . indicate free space and the x's show the positions of the resistors
