Question 34 of 34
Find one or two real transformers and bring them with you to class for discussion. Identify as much information as you can about your transformers prior to discussion:
- Winding ratio(s)
- Winding resistances
- Voltage rating of each winding
- Current rating of each winding
- Frequency rating
- Application (power, signal, audio, etc.)
- Type (iron core, air core, etc.)
Reveal answerIf possible, find a manufacturer’s datasheet for your components (or at least a datasheet for a similar component) to discuss with your classmates.
Be prepared to prove the actual winding resistances of your transformers in class, by using a multimeter!
Notes:The purpose of this question is to get students to kinesthetically interact with the subject matter. It may seem silly to have students engage in a “show and tell” exercise, but I have found that activities such as this greatly help some students. For those learners who are kinesthetic in nature, it is a great help to actually touch real components while they’re learning about their function. Of course, this question also provides an excellent opportunity for them to practice interpreting component markings, use a multimeter, access datasheets, etc.
Creative and interesting excercises.
