A step-down transformer has 3000 turns on its primary coil and 20 turns on its secondary coil. The primary circuit is supplied with an effective AC voltage of 325 V. a. What is the voltage in the secondary circuit?

b. If the current in the primary circuit is 1.25 A, what power is drawn by the primary circuit?

c. Assuming the transformer is perfectly efficient, what power is supplied to the secondary circuit?
