Could you please work these step by step? These are severalpracticeproblems I am struggling with. Thank you in advancefor the help--will rate lifesaver!
1) A transformer quadruples a primary voltage of110v (ac).What is the ratio of the number of turns in itsprimary coil tothose in the secondary coil?
A) 4:1
B) 1:4
C) A or B
D) need more info
2) The primary coil of a transformer has 100turnsand its secondary coil has 400 turns. If the ac currentin thesecondary coil is 2A, what is the current in its primarycoil?
A) 8A
B) 1/2A
C) 4A
D) 2A
E) 1/4A
