Metal Oxide Varistor

MOV is a video format that was developed by Apple. It's an MPEG 4 video container file that is primarily used with Apple's QuickTime program. An MOV video can hold many different video formats and multimedia — audio, video, and text — in the same file on different tracks.

A varistor is a surge protecting electronic component with an electrical resistance that varies with the applied voltage.^[2] It has a nonlinear, non-ohmic current–voltage characteristic that is similar to that of a diode. Unlike a diode however, it has the same characteristic for both directions of traversing current. Traditionally, varistors were indeed constructed by connecting two rectifiers, such as the copper-oxide or germanium-oxide rectifier in antiparallel configuration. At low voltage the varistor has a high electrical resistance which decreases as the voltage is raised. Modern varistors are primarily based on sintered ceramic metal-oxide materials which exhibit directional behavior only on a microscopic scale. This type is commonly known as the metal-oxide varistor (MOV).
