ELEC21B
Module 21B: Cells and Small Voltage Sources B (Optional)
Outcome
Investigate methods of producing electrical energy.
Indicators
| (a) | Compare the characteristics of different energy sources (e.g., light energy, chemical energy, heat energy, piezoelectric effect, friction and mechanical-magnetic). |
| (b) | Explain how electrical energy is produced from different sources. |
| (c) | Test for the presence of a static electric charge on an object (e.g., ebonite or plastic rod rubbed with fur). |
| (d) | Measure the voltage produced by a simple voltaic cell. |
| (e) | Investigate the operation of a thermocouple. |
| (f) | Examine how a piezoelectric device (e.g., phonograph pick up cartridge) can generate electrical energy. |
| (g) | Explore how to generate electrical current using a permanent magnet and a coil of wire. |
