Sometimes finance deals with negative quantities that become less negative over time. For example, consider a profit/(loss) of ($50M) in year 1 that becomes a profit/(loss) of only ($1M) in year 4. If we apply the traditional formulas for Percent Change and Compound Annual Growth Rate (CAGR), we find that the results do not align […]
An NTC (Negative Temperature Coefficient) Thermistor is a passive electrical component whose resistance varies inversely with temperature.i It is often used as a temperature sensor. The relationship between resistance and temperature can be described with the ‘beta’ formula. In this experiment we will show how to use the National Instruments myDAQii in conjunction with LabVIEWiii […]
