(a)Design a PZT piezoelectric spark generator that can provide 65 µJ spark in an air gap of 0.5 mm from a force of 70 N. The following constraints have to be satisfied. (i) PZT crystal has to be selected from Table A2. (ii) The space in the spark generator for the selected PZT crystal is limited to 5 mm³. PZT1 PZT2 PZT3 PZT type D (PC N-¹) 682 490 578 Er 3400 2290 3270 Table A2 Assume that the spark gap operates at one atmosphere (105 Pa) and the breakdown voltage for the air gap follows Paschen's curve as shown in Figure A2. The design will also need to specify the dimension of the crystal. Air Thy Teming 10 10² 10³ Pressure x Spacing (Pa m) Figure A2 Breakdown Voltage (V) to TOFTE FREE TURE 10-¹ 1
