Answer: The difference in voltage (110V vs. 220V) across countries is primarily due to historical, economic, and technical factors. Reasoning: The choice between 110V and 220V systems largely depends on historical development, economic considerations, and technical requirements. Countries like the United States and Japan typically use 110V due to early …

Answer: Transformers are not used in direct current (DC) systems because they rely on the principle of electromagnetic induction, which requires a changing magnetic field to induce voltage and current in the secondary winding. In a DC system, the current flows in a constant direction, creating a steady magnetic field …
