A transformer has 2400 primary turns and 600 secondary turns. If the primary is supplied from a 220 VAC supply, which one of the following gives the resultant secondary voltage? A. 55 V B. 110 V C. 880 V A transformer has 1200 primary turns and 60 secondary turns. What is the primary current if secondary current is 20 A? A. 1 A B. 0.5 A C. 2 A A transformer is wound with 100 turns on the primary and 450 turns on the secondary. The primary voltage is 250 volts. Find the secondary voltage? A. 1125 volts B. 55.5 volts C. 112500 Volts Homework 9 (Transformer Questions) 1. If the primary winding of a transformer has more turns than the secondary winding, what type of transformer is it? If the primary has fewer turns, what type of transformer is it? 2. The secondary voltage of an iron-core transformer is calculated based on the following data: • Primary voltage = 240 V • Primary current = 40 A • Secondary current = 20 A • What is the secondary voltage? 3. A transformer has 250 turns in its primary winding. . To double the voltage, how many turns must the secondary winding have?
