Lesson 2: Energy Source

Energy is defined as the ability to do work. Direct current sources supply electrical energy through the transformation of chemical or some other kind of energy. Do all DC sources have identical energies?

Doing the science

1. Click the "Simulation" button to open the Betavoltaics sim.
2. Click on one of the direct current sources located at the top of the screen.
3. Click the red "Start" button on the source testing device.
4. Record the source name and the amount of energy in Table 1.
5. Repeat steps 2–4 above, until all sources are tested. Make sure to record your data in Table 1.
