Step up transformer calculations

The video tutorial explains the functioning of step-up transformers, focusing on how they increase voltage while decreasing current. It provides examples and formulas for calculating voltages, turns, and currents on both primary and secondary sides. The tutorial also emphasizes the importance of power consistency across the transformer. The session concludes with a summary of the key points discussed.

What happens to the voltage and current when using a step-up transformer?

If a transformer has 100 turns on the primary and 200 on the secondary, what is the output voltage 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 primary current if you know the secondary current?

Explain how to check if the power is the same on both sides of a transformer.
