Step Down Transformer Calculations

The video tutorial explains the basic principles of transformers, focusing on how they change voltage and current. It demonstrates calculations for output voltage, number of turns, and current on both primary and secondary sides using specific formulas. The tutorial emphasizes the importance of power consistency across the transformer and concludes with a summary of the key points covered.

What is the output voltage of a transformer with 1000 turns on the primary and 100 turns on the secondary when supplied with 120 volts?
