Explanation:
By symmetry, the currents in the resistors must be distributed as shown below
Applying Kirchoff's Voltage law to the loop ACEBA gives :
while the loop CHGEC gives
The two equations together give
The net voltage drop across thee circuit = the voltage drop along the path ACH =
Thus, the effective resistance between A and H is
