In this case, you will get an equation of the form . If you find the equation in this way, calculate using the formula . K 4. Redisplay the graph and use the calculator’s trace function to move the cursor along the data plot. Determine the approximate time at which the capacitor voltage reached half its initial value. This value is sometimes called the value, denoted half-life t1/2. Record the value in the Data Table. It represents the time required for a quantity that is decaying exponentially to reach half its starting value. You can compare the value of to the parameter you determined in the model, using this t1/2 K formula for determining half-life Use the formula and the value determined in Step 3 to compute a value of and record it K t1/2, in the Data Table.
