Abstract
Temperature -Capacitance relationship was investigated using polycarbonate Compact Disc (CD). Ideally, a capacitance of a capacitor would be the same at all temperatures. But in reality, capacitance changes as the capacitance gets warmer or cooler. In many cases, these changes are ignorable but since research is always engage in a very precise experimental value results, determining the capacitance value or dealing with very large temperature swings are must take into considerations. In this study, in the absence of capacitor, the capacitance has been measured. The polycarbonate resins were placed in a small beaker, surrounded by 12 electrodes connected to LCR to measure the capacitance, and heat was continuously applied and the thermocouple placed in the middle of the beaker connected to the tester to measure the temperature in terms of voltages output. The experiment was repeatedly done using different beaker diameter sizes for data comparisons aiming to discuss how the capacitance change with temperature and what is the factor has caused of this change. Using the Electrical Computer Tomography (ECT), the gathered numerical data was used in calculations for image reconstructions using non-iterative Functional Weighted Inverse Matrix method.
