A transformer with 100% efficiency has 6000 turns on the primary coil and 600 turns on the secondary coil. The transformer’s output voltage is $12\,\text{V}$. A resistor is connected across the secondary coil and dissipates $24\,\text{W}$ of power. What current flows in the primary coil of the transformer?
- A$0.050\,\text{A}$
- B$0.20\,\text{A}$
- C$5.0\,\text{A}$
- D$20\,\text{A}$
