There used to be a version that used rotating disks, but the normal kind used for broadcast TV in the UK, USA, etc. used a CRT.
To make the picture, an electron gun scans across the inside of an evacuated tube with
a phosphor on the inside. When the electrons hit the phosphor it glows white. To make the spot brighter, the electron current is increased. The brightness signal is encoded with
sync pulses (which control the scanning of the beam) and modulated onto a radio wave for transmission.
Originally, a similar vacuum tube technology (vidicon tube) was used for the camera. A lens
focuses a picture onto a photo-sensitive material, and an electron beam scans across it.
Where the photons of light displace electrons from the material, there is an increased current
which is amplified and used to generate the radio signal.
The sound is modulated onto a separate subcarrier and transmitted along with the picture.
The television (telly) works by receiving electromagnetic signals through an antenna or cable, which are then converted into images and sound by the TV's circuitry. The images are displayed on the screen using pixels that light up to create the picture, while the sound is produced by speakers within the TV.
No, a sofa is not a conductor. Conductors are materials that allow the flow of electrical current, while sofas are typically made of non-conductive materials like wood, fabric, and foam.
The formula that relates work and power is: Power = Work / Time. Power is the rate at which work is done, which is the amount of work done divided by the time it takes to do that work.
The work that a simple machine does is called mechanical work. It refers to the amount of force applied over a distance to accomplish a task using the simple machine.
work output
Actually, the work done on a machine is referred to as mechanical work. It involves the application of force to move an object over a distance, such as pushing a button or turning a knob on a machine.
