Chapter 23, Problem 45P
Engineers testing an ultracapacitor (see Application on page 420) measure the capacitor’s stored energy at different voltages. The table below gives the results. Determine a quantity that, when you plot stored energy against it, should give a straight line. Make your plot, establish a best-fit line, and use its slope to determine the capacitance.
Voltage(V) | 12.2 | 20.1 | 31.8 | 37.9 | 45.7 | 50.2 | 56.0 |
Energy(kJ) | 9.25 | 27.2 | 62.5 | 94 | 139 | 158 | 203 |
