Cube R network resistor calculation

Click For Summary
SUMMARY

The equivalent resistance from point D to point B in a cube resistor network is calculated to be 3/4 R. This conclusion is drawn from the mirror-symmetry of the network through a line connecting points A and C. The symmetrical properties of the cube allow for simplification in the analysis of the circuit, confirming the resistance value with respect to the resistors involved.
