information about piezoelectric transducer

Really, It's it simpler to Google than to demonstrate your ignorance here.

Wow, that was cold.

I kind of like it.

I have no problem trying to help answer someone's question, but at least google it first for the basics then ask us specific questions.

I don't know why it bothers me so much, but, you'd think that people would have the courtesy to at least frame an informed question.

Google first, keep the ignorance factor lower.

I started a thread a while back called "Google it" for just this reason. Some people agreed with me and others seemed to think that I was wrong to suggest that google should be a first option. Some times you just can't win.

I do feel that getting some info first, then formulating a responsible question is best.
