Questions & Step-by-Step Solutions
What is the typical frequency of transformers used in power systems?
Step 1: Understand what a transformer is. A transformer is a device that changes the voltage of electricity.
Step 2: Know that transformers can work at different frequencies. Frequency is how often the electricity changes direction in one second.
Step 3: Learn that the most common frequencies for transformers in power systems are 50 Hz and 60 Hz. This means the electricity changes direction 50 or 60 times every second.
Step 4: Recognize that 400 Hz is used in special cases, like in aviation, where lighter and smaller equipment is needed.
