Click the link and watch a video I have posted showing exactly how to wire this configuration.
That is called 4 way intermediate switch wiring. Click the link to watch a video I have posted showing how to wire just such a circuit.
Tesla invented the electric generators as the patent shows the date to be 1888. He was from Croatia.The scientist tesla is from this country he invented electrical generators?
The benefits from technology include communication being more efficient and faster. Technology helps in the medical field with research and maintaining patient records. Computers have opened up distance learning and new methods of teaching.
What you may be referring to, since the question was posted in electrical engineering section, is in reference to the electrical switches and devices installed on sprinkler systems. The systems have water flow devices, low air switches, valve tamper devices and the like. each device is designed to monitor changes in state in the system. (sprinkler waterflow, low air pressure in a system, an improperly open or closed valve, to name a few.) these devices are designed to send an electrical current or signal of high or low voltage to a device(bell or siren) or to an alarm or control panel. The terminals on these devices are similar. They have a "common" terminal. Next, they have an "normally open" terminal; which means the circuit is open normally, but closes during a change in state. The circuit is supervised with a end of line resistor in the circuit, hence an "open loop"
75 mph
Posted speed limits tell you what the maximum speed is on that specific road. That is the speed that you are legally able to drive on the road.
The maximum speed limit in Florida is 55 mph, except where otherwise posted. Speed limits are 70 mph on some rural interstate highways.
For safety.
Parts of the German Autobahn do not have posted speed limits.
The maximum speed limit on the highway in Florida is 65 mph unless otherwise posted. Speed limits are 70 mph on some rural interstate highways. Never assume that just because the area appears to be rural, the limit is 70 mph. Speed limits may change on other multi-lane highways.
operating locations
Roads are built for safety and speed limits are determined by the conditions of the road on which they are posted.

The distance is ~475 miles. Allow 8 or 9 hours for the trip if running at posted speed limits.
