Questions & Step-by-Step Solutions

What is the typical frequency of operation for power transformers?
  • Step 1: Understand what a power transformer is. It is a device that changes the voltage of electricity for transmission and distribution.
  • Step 2: Learn about frequency. Frequency refers to how many times something happens in one second. For electricity, it is measured in Hertz (Hz).
  • Step 3: Know the common frequencies for power transformers. In most parts of the world, power transformers operate at either 50 Hz or 60 Hz.
  • Step 4: Identify the regions. 50 Hz is commonly used in Europe, Asia, and Africa, while 60 Hz is used in North America and some other areas.
  • Step 5: Conclude that the typical frequency of operation for power transformers is either 50 Hz or 60 Hz, depending on the region.
