They do different jobs!
What does a transformer do?
Think about your electrical appliances.
True or False: The secondary coil always has more turns than the primary in a step-down transformer.
Remember how it changes the voltage.
Design a transformer with a primary voltage of 240V and a secondary voltage of 120V. How many turns would be required in each coil if the primary has 300 turns?
Remember to relate the turns to the voltage!
