Question

You might have observed on a dry day that when you touch the screen of a television or computer monitor (with a picture tube), you get a slight shock. Why does it happen?

Answer 1

Picture tube:

1. A television's picture is shown on a cathode-ray tube.
2. We get minor shock by touching the picture tube monitor or television because the television screen or computer monitor is charged and has static charges accumulated on the surface.
3. So, when we touch the surface of a monitor or television with an uncharged hand the charges flow through our hands and we receive a small shock.

Hence, we get a minor shock by touching the picture tube television or monitor due to the flow of charge through our hands.
