Yoke
The yoke is the electromagnetic coil located on the neck of the picture tube or tubes in a television or monitor. It is responsible for pulling the electron beam from side to side and up and down, allowing for the proper scanning of the screen to create the image.
Function
- The yoke generates a magnetic field that controls the movement of the electron beam, ensuring that it scans the screen in a precise and controlled manner.
- By adjusting the current passing through the yoke coils, the position of the electron beam can be manipulated to create the desired image on the screen.
Construction
- The yoke consists of two sets of coils wound around a ferrite core. These coils are typically arranged perpendicular to each other to control horizontal and vertical movement of the electron beam.
- The number of turns in each coil and the current passing through them determine the strength of the magnetic field produced by the yoke.
Importance
- The yoke plays a crucial role in ensuring that the electron beam scans the screen accurately, resulting in a clear and sharp image.
- Without the yoke, the electron beam would not be properly controlled, leading to distorted or incomplete images on the screen.
In conclusion, the yoke is an essential component in a television or monitor that controls the movement of the electron beam to create the images we see on the screen.
