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?

How can you find the input voltage if you only know the output voltage and the number of turns?

What formula would you use to find the number of turns on the secondary side if you know the voltages and primary turns?

If the secondary current is known, how can you find the primary current?

What is the relationship between voltage and current on both sides of the transformer?
