#Notice# The voltage source in Fig.(b) had the wrong symbol, howerver, it is indeed a voltage source, not a current source.
根据本图回答以下(1) (2)题:1) For an ideal transformer in Fig. (a), we know that the number of the turns in the primary side is $ {N_{\rm{1}}}$, and the number of the turns in the secondary side is $ {N_{\rm{2}}}$, The primary side connects the current source ${\dot I_{\rm{S}}} $, and the secondary side connects the resistor $R $. If the output power of the secondary side increases, then the turns in the secondary side should be a) increased b) decreased?
