The meter was defined in 1792 as 1/10,000,000 of the distance between the North Pole and the equator on a line running through Paris, France. The standard length of a meter was later changed to be the distance between two fine lines engraved on a bar of platinum and iridium alloy. The next definition was based on the wavelength of light emitted by an isotope of the element krypton. The present definition, in use since 1983, is the distance light travels in a vacuum during approximately one three hundred millionths of a second (1/299,792,458 sec).
What else can I help you with?
When installing lights with 2-way and intermediate switching control the intermediate switch must be connected to the?
to wire a lamp to be controlled from three places you need two three way switches and one four way switch. the two traveller wires that would normally run between the two three way switches must be connected to the terminals of the four way switch
How can an intermediate switch be used with a 2-way switch system to control a light from four floors?
A two way switch is UK terminology for a North American three way switch. Though the switch has two names it is still a Single Pole Double Throw switch that has three terminals. North American terminology. The circuit is the same as the three way switch system. To control from four locations just add another intermediate switch. For the system to work properly the new intermediate switch has to be adjacent to the existing intermediate switch. The connections must run - three way, intermediate, intermediate, three way.
What is Three state switch?
A three-state switch is an electrical switch that can operate in three distinct positions: ON, OFF, and an intermediate or "high-impedance" state. This intermediate state effectively disconnects the circuit, allowing for greater flexibility in applications such as digital circuits, where it can prevent unwanted interactions between components. Commonly used in applications like data buses, three-state switches help manage multiple signals on a single line without interference.
How would a three phase meter reading compare to three single phase meters connected to the same service?
The reading on the 3-ph meter would equal the sum of the three separate readings on the single-phase meters. The neutral sides of the single phase meters do not need to be connected to the neutral wire as long as they are connected together.
What is the most stable microtubules microfilaments or intermediate filaments?
Intermediate filaments are generally considered the most stable among the three cytoskeletal elements (microtubules, microfilaments, and intermediate filaments). They are more resistant to changes in cell structure and provide structural support and stability to the cell.
Write three numbers that are between 2.15 meter and 2.17 meter?
2.155, 2.16 and 2.165 meters
What is the relationship between 75 centameters and 1 meter?
75 cm equals three quarters of a meter
What are the times between the three major periods of Egyptian history called?
The three major periods of Egyptian history are the Old Kingdom, Middle Kingdom, and New Kingdom. The times between these periods are referred to as the Intermediate Periods. Specifically, the First Intermediate Period occurs between the Old and Middle Kingdoms, while the Second Intermediate Period falls between the Middle and New Kingdoms. These periods are characterized by political instability, fragmentation, and sometimes foreign invasions.

Is longer three feet or a meter?
A meter is a bit longer than three feet.
How long is three meter sticks?
Three meter sticks would measure a total length of three meters. Since each meter stick is one meter long, the combined length is simply the sum of the individual lengths. Therefore, three meter sticks together equal three meters, or 300 centimeters.
