Mr. X and Mr. Y are two friends. One day they were walking on the street and saw that a man in a strange dress has shown many magical activities. He introduced a crystal that turned on the LED light by giving pressure on it. Everyone was surprised by that activities. But Mr. Y said that this crystal is a piezoelectric transducer and is also known as a self-transducer. It can't generate high voltage. For increasing voltage level extra devices are needed. a) Why it is called self-transducer? b) could you explain what are the main reason for generating the low output voltage? c) “For increasing voltage level extra devices are needed” justify this statement.
