**Equivalent resistance of the parallel combination is**

R_{p }= \(\frac{r_1\,\times\,r_2}{r_1\,+\,r_2}\)

= \(\frac{5\,\times\,10}{5\,+\,10}\)

= \(\frac{50}{15}\)

= \(\frac{10}{3}\,\Omega\)

**These eight resistances are connected in series, so**

**So, the equivalent resistance of the combination is \(\frac{80}{3}\,\Omega\)**
