1. Both piezoelectric crystals with voltage sensitivity of 100 Vm/N having Cp= 1600 pF and a leakage resistance of 10^12 ohm are connected to amplifier as shown below. what will be the output of this op-amp? 80 k2 80 k2 20 k2 40 k2 Thickness=0.1 mm F=10 Length =7 m Width=3 m ww- 20 k2 Thickness=0.1 mm F=0.2sin1000t Length =7 m Width=3 m Q.2. 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. 1.
