# What is the resultant resistance of the circuit [closed]

If all resistants have a resistance of $R$, find the resultant resistance between points $AE$.

My Try: Since Points AB and AC have equal resistance, There's an equal current flowing through each branch. So points B and C have equal voltage compared to point A. So we can delete resistant between B and C. Similarly resistant between C and D can be removed. So the top branch would yield $3R$. Bottom branch would yield $2R$. Since those two branches are parallel. Then resultant would be $\frac{6R}5$. Is this method Correct? Or can we just seperate nodes at C as in the following diagram to make it 'less complicate'?

• Thanks for letting me know. I'll ask for the concept instead of the answer. – emil Aug 2 '18 at 7:32
• One thing to look for is symmetry. In this case what can you infer about the potential of the node midway between Band D and the potential at node C? – Farcher Aug 2 '18 at 9:11
• They are equal. So we can break resistance in path BD into two $\frac{R}{2}$ 's and join midpoint of that to node C? Am I correct? – emil Aug 2 '18 at 9:33
• "Since Points AB and AC have equal resistance, There's an equal current flowing through each branch." - This would only be valid if you stipulate that the (node) voltage at B equals the voltage at C. Concluding that which you stipulate is begging the question – Alfred Centauri Aug 2 '18 at 13:01
