4. (3 points) The diagram below represents two parallel current-carrying conductors. As indicated, the current is moving out of the page for both conductors. Determine whether the conductors attract or repel each other, and explain your reasoning. 5. (2 points) A step-down transformer at a distribution substation accepts a voltage of 4.80 x 10' V and a current of 5.50 A from the power line. The voltage of the transformer's secondary coil is 1.20 x 104 V (a) (1 point) Determine the transformer's power. (b) (2 points) What is the current in the secondary coil? (c) (1 point) What is the ratio of the number of turns between the primary and secondary coils in this transformer
