Consider the icosahedral resistance network shown in the following figure. Each edge is made of a rod of resistance $r$. Select the option(s) that is(are) correct:

A) The resistance between points A and B is $\frac{r}{2}$
B) The resistance between points A and B is \$\frac …

## An Interesting Electronics Problem
