A transformer has an input voltage of $240\,\text{V}$ and an output voltage of $12\,\text{V}$. What could be one possible pair of values for the number of turns in the primary coil and the number of turns in the secondary coil?
- Aprimary coil: 12, secondary coil: 4800
- Bprimary coil: 240, secondary coil: 4800
- Cprimary coil: 4800, secondary coil: 12
- Dprimary coil: 4800, secondary coil: 240
