A torch has three lamps arranged in parallel, and it is supplied by a cell with electromotive force (e.m.f.) $3.0\,\text{V}$ and negligible internal resistance. The power dissipated by each lamp is $0.60\,\text{W}$. What current flows in the cell?
- A$0.067\,\text{A}$
- B$0.20\,\text{A}$
- C$0.60\,\text{A}$
- D$0.83\,\text{A}$
