How Transformers Increase Voltage

The video tutorial explains how transformers work by altering voltage and current through different wire turns on the primary and secondary sides. It emphasizes the conservation of power, where the product of voltage and current remains constant. The tutorial also clarifies why transformers are rated in KVA instead of kilowatts, due to the unknown load and power factor. The concept of power factor is introduced, highlighting its role in efficiency and reactive power. An analogy using a glass of beer is used to illustrate the relationship between true power, reactive power, and apparent power.
