1) The cross-sectional area of the core of a 1.2-kVA, 120/208-V, 50-Hz ideal transformer is 100 cm^2. The primary has 60 tuns. Calculate

(a) the induced emf per turn,

(b) the number of turns in the secondary, and

(c) the effective flux density in the core.

2) A power amplifier can be represented by a current source in parallel with a 200ohm resistance. An 8-ohm loudspeaker is connected to the power amplifier via an audio transformer so that maximum power is transferred to the loudspeaker. What must be the a-ratio of the transformer?
