To find the equivalent resistance between terminals A and B of a cube made of 12 resistors, each of resistance R, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Cube Configuration**: The cube has 12 edges, and each edge has a resistor of resistance R. When terminals A and B are connected to an EMF source, the current will flow through the resistors along the edges of the cube. 2. **Symmetry of the Cube**: ...
