  • Q3. Why and which type of transformer do we use to reduce power loss during transmission?
  • Ans. 

    We use step-up transformers to reduce power loss during transmission by increasing voltage and decreasing current.

    • Step-up transformers increase voltage and decrease current, which reduces power loss during transmission.

    • This is because power loss is proportional to the square of the current, so reducing current reduces power loss.

    • For example, power is transmitted over long distances at high voltages (e.g. 500 kV) to red...
