Answers

Answer 1

Even when unplugged, a CRT (Cathode Ray Tube) monitor can store a lot of electricity. The capacitors within CRT monitors can store enough power to be fatal, thus you should never open one.

What does CRT stand for?

An electron beam striking a phosphorescent surface creates images in a cathode-ray tube (CRT), a specialized vacuum tube. CRTs are typically used for desktop computer displays. The "picture tube" in a television receiver is comparable to the CRT in a computer display.

What characteristics does CRT have?

Flat screen, touch screen, anti-reflective coating, non-interlaced, industrial metal cabinet, and digital video input signal are typical features of CRT monitors. As opposed to the typically curved screen found in most CRT displays, the monitor's screen can be (almost) flat.

Answer 2

Answer:

CRT monitor

Explanation:

A cathode ray tube (CRT) monitor can store large amounts of electricity, even when unplugged. You should never open a CRT monitor, as the capacitors within the CRT can store enough electricity to be lethal.

LCD monitors do not use large capacitors and are much safer to work on than CRT monitors (although the CCFL backlight has mercury vapor in it, which could be harmful if the tube is broken).

DVD optical drives and hard disk drives do not store electricity in sufficient quantity to be harmful.
