4-3.The primary of a transformer has 200 turns and is excited by a 60-Hz, 220-V source. a. Find the maximum value of the core flux. b. Let a voltage v

= 155.5 sin 377t + 15.5 sin 1131t (V) be applied to the transformer primary. Neglecting leakage, determine the instantaneous and rms values of the core flux.
