In a transformer, the primary coil has $N_p$ turns and the secondary coil has $N_s$ turns. The potential difference across the primary coil is $V_p$, while the potential difference across the secondary coil is $V_s$. What link exists between these four quantities?
- A$V_p \times V_s = N_p \times N_s$
- B$\frac{V_p}{V_s} = \frac{N_p}{N_s}$
- C$\frac{V_p}{V_s} = \frac{N_s}{N_p}$
- D$\frac{V_p}{V_s} = N_p \times N_s$
