Two coils are wound on a toroidal core as illustrated in Figure . The reluctance

of the core is 10⁷ (ampere-turns)/Wb. Determine the mutual

inductance of the coils.

Suppose that we have a 4700-V-rms ac source and we need to deliver 220 V rms to a

load. Determine the turns ratio N1/N2 of the transformer needed.
