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.
