Module 5C: Electrical Principles - Alternating Current and Direct Current (Core)
Outcome
Differentiate between alternating current (AC) and direct current (DC).
Indicators
| (a) | Explain the operating principles of AC and DC. |
| (b) | Research the history of the competition between supporters of AC and DC. |
| (c) | Identify common applications of AC (e.g., house wiring and distribution of power) and DC (e.g., cell phones, flashlights and hybrid cars). |
| (d) | Explain why either AC or DC may be preferable for specific applications. |
| (e) | Draw common AC and DC waveforms. |
| (f) | Observe a sine wave and label the characteristic parts including cycle, wavelength, wave height, period and frequency. |
