What is the primary function of a transformer?
Think about power distribution.
Define mutual induction.
Focus on the relationship between the coils.
What does a step-up transformer do?
Think of how voltage changes in transformers.
True or False: A step-down transformer increases voltage.
Recall the function of a step-down transformer.
Design a transformer that will convert 240V AC to 60V AC. The primary coil has 1200 turns. How many turns should the secondary coil have?
Remember to set up your proportion correctly based on the transformer principles.
Calculate the efficiency of a transformer given the following parameters: output power is 900W, input power is 1000W.
Efficiency is a measure of how much input power is converted into output power.
