Questions & Step-by-Step Solutions
What is the typical efficiency range of a power transformer?
Step 1: Understand what a power transformer is. It is a device that transfers electrical energy between two or more circuits through electromagnetic induction.
Step 2: Learn about efficiency. Efficiency in this context means how well the transformer converts input electrical energy into output electrical energy without losing too much energy.
Step 3: Know the typical efficiency range for power transformers. This means that most power transformers can convert 90% to 98% of the input energy into usable output energy.
Step 4: Realize that this efficiency range indicates that only a small amount of energy (2% to 10%) is lost as heat or other forms of energy during the transformation process.
