Identify the expression for transformation ratio from the following.

A. k = \(\frac {V_s}{V_p}=\frac {I_s}{I_p}=\frac {N_s}{N_p}\)
B. k = \(\frac {V_s}{V_p}=\frac {I_s}{I_p}=\frac {N_p}{N_s}\)
C. k = \(\frac {V_s}{V_p}=\frac {I_p}{I_s}=\frac {N_s}{N_p}\)
D. k = \(\frac {V_p}{V_s}=\frac {I_s}{I_p}=\frac {N_s}{N_p}\)
Answer» D. k = \(\frac {V_p}{V_s}=\frac {I_s}{I_p}=\frac {N_s}{N_p}\)
