Transformers P and Q each have 2000 turns on the primary coil and 1000 turns on the secondary coil, and both operate at 100% efficiency. The secondary coil of transformer P is linked to the primary coil of transformer Q. Transformer Q supplies a motor with a current of $0.2\,\text{A}$. What current is supplied to the primary of transformer P?
- A$0.8\,\text{A}$
- B$0.4\,\text{A}$
- C$0.1\,\text{A}$
- D$0.05\,\text{A}$
