Question 23 5 pts A transformer is being used to step-down the voltage from 120V to 12 V for use with a portable CD player. Which of the following statements are true in regard to the properties of the transformer? Assume that 120 V corresponds to the voltage in the primary coil and 12 V to the voltage in the secondary coil. O a) The current in the secondary coil is larger than that in the primary coil b) The number of loops in the primary coll is greater than in the secondary coil. Oc) The electric power generated in the primary and secondary coils is identical, O d) All of the above e) Botha and b.
Question 24 5 pts Refer to question 23 If there are 5 loops in the secondary coil, how many loops are there in the primary coll? O a) 100 loops O b) 75 loops c) 50 loops d) 25 loops O e) 10 loops 5 pts
