Lesson 3: Safety and Electrical Power
Computers are electronic equipment and therefore consume electricity. Although most components in a computer operate on low voltages-in the safe range between 3.3 and 12 volts DC-the main power source and the monitor use high voltages. This lesson sets out some basic high-voltage electrical safety guidelines.
After this lesson, you will be able to:Estimated lesson time: 5 minutes
- Identify high-voltage hazards.
- Define some common guidelines for electrical safety.
