# Question: An ac generator supplies 20 A at 440 V to

An ac generator supplies 20 A at 440 V to a 10 000-V power line through a step-up transformer that has 150 turns in its primary coil.

(a) If the transformer is efficient (see Exercise 32), how many turns are in the secondary coil?

(b) What is the current in the power line?
