Question 25 of 25
Find one or two silicon-controlled rectifiers and bring them with you to class for discussion. Identify as much information as you can about your SCRs prior to discussion:
- Terminal identification (which terminal is gate, anode, and cathode)
- Continuous voltage rating
- Continuous current rating
- Continuous power rating
- Whether or not it is a ßensitive gate” device
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 terminal identifications of your SCRs 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.
Can someone please explain why do we need C1 capacitor in question 22 ? Circuit behaves exactly the same without it and I am confused about it’s purpose.
