Problem

For an ideal transformer, which of the following relations between the rms voltages VpV_p and VsV_s and the turn numbers NpN_p and NsN_s is correct? (a) VsVp=NpNs\dfrac{V_s}{V_p}=\dfrac{N_p}{N_s} (b) VsVp=NsNp\dfrac{V_s}{V_p}=\dfrac{N_s}{N_p} (c) VsVp=IsIp\dfrac{V_s}{V_p}=\dfrac{I_s}{I_p} (d) VsVp=(NsNp) ⁣2\dfrac{V_s}{V_p}=\left(\dfrac{N_s}{N_p}\right)^{\!2}
