In the circuit diagram, the battery provides an electromotive force (e.m.f.) of $6.0\,\text{V}$ and has negligible internal resistance. Each of the three resistors has resistance $R$. The total power dissipated by the resistor network is $24\,\text{W}$. Determine the value of $R$.
- A$0.50\,\Omega$
- B$1.0\,\Omega$
- C$1.5\,\Omega$
- D$2.3\,\Omega$
