The network contains a $3.0\,\Omega$ resistor together with two $6.0\,\Omega$ resistors, as illustrated. The potential difference (p.d.) across the network is $4.0\,\text{V}$. What current flows through the $3.0\,\Omega$ resistor?
- A$0.17\,\text{A}$
- B$0.25\,\text{A}$
- C$0.33\,\text{A}$
- D$1.3\,\text{A}$
