A resistor and a filament lamp are connected in series to a power supply. The $I\text{-}V$ characteristics for the resistor and the lamp are shown. The potential difference (p.d.) across the resistor is $3.3\,\text{V}$. What is the resistance of the lamp?
- A$0.071\,\Omega$
- B$4.2\,\Omega$
- C$11\,\Omega$
- D$14\,\Omega$
