We will see how much energy we can get from these sources and at what rate the energy can be produced. You will publish the results of today s experiments to the web. By choosing File Edit Page from Netscape, you can type your answers directly into the boxes on that page. You may either do this as you go, or all at once when you have all the data and calculations finished. Make a note of the file name you give this report, so that you can create a link from your homepage to this new report page.
Batteries turn chemical energy to electrical energy.
You will discharge a AA battery with a known resistance and measure the voltage as the battery is used. The voltage from a battery doesn t remain at 1.5 V, but decreases as the battery dies, so we will make measurements at several times and average these. Wire the circuit as shown to the right, using the spring-loaded connectors coming from the blue box sitting on top of the computer. Connect the red lead to the wire coming from the positive end of the battery and the black lead to the other wire. Then, once every 100 s it will record an additional data point.
