An ideal transformer with a 300 turn primary connected to a 480 V, 60 Hz supply line needs to output 120 V from the secondary. If a 100 h resistor is connected across the secondary, determine: A. How many turns the secondary must have to output the desired voltage. B. The current through the resistor. C. The current drawn through the primary. D. The maximum flux in the core of the transformer.
