Which of the following computer components retain a significant lethal electrical charge even after the device is unplugged?
  1. Monitor
  2. Processor
  3. RAM
  4. Hard drive
  5. Keyboard
Explanation
Answer - A - Monitors operate at high voltages with a high amount of electric charge. CRT monitors can store up to 24 KV. Hence the back of the monitor should not be opened unless you are trained to do so.

Key Takeaway: Of the components mentioned here, only monitors store a high amount of static electricity. Components like processor, RAM and hard drive do not store the amount of static electricity that could prove lethal.
