How Does A TV Work?

A tv is for transmitting and receiving moving images that can be black and white or coloured with a sound.

Paul Nipkow invented the TV in 1884,he invented the first tv in black and white.

A TV is powered by a power satellite that brings you channels. You have a button on the screen on the side that you put the TV on. satellite dishes pick up signals which are sent into space by television stations and bounced back to earth off satellites.

Some people used TV set for business, so they can get information on what is the weather or what is going on in the world.
