A mercury arc valve converts high-voltage or high-current alternating current into direct current. It is an electrical rectifier often used to provide power for industrial motors, electric railways, streetcars, and electric locomotives. Peter Cooper Hewitt, in 1902, invented the mercury arc rectifier. It was further developed by researchers throughout the 1920s and 1930s. Prior to solid-state devices, mercury arc rectifiers were one of the more efficient rectifiers. Silicon diode and...

Only one terrestrial planet,...
The Solar System refers to the area in space that is dominated by our own Sun. It is comprised of the Sun and its associated astronomical objects that are held in its gravitational orbit. The Solar System was formed as a result of the collapse of a giant molecular cloud approximately 4.6 billion years ago. The mass of this system is located almost entirely in the Sun. Apart from the Sun, a high percentage of the remainder of the system’s mass is located in the eight solitary planets that...
