Part 3/6:
This portion of the experiment underscores the dynamic behavior of barium titanate when subjected to stress, confirming its potential for energy conversion applications.
Charging and Spark Generation
Next, Paul sets aside his measurement tools and allows the cylinder to charge over a 15-minute interval. He then attempts to discharge stored energy by creating a spark, listening carefully for the high-pitched crackle associated with electrical discharge. Indeed, he reports hearing a distinctive sound and observes a spark, demonstrating the material's ability to generate visible electrical energy.
