How fast to turn on a light in Los Angeles, from Chicago

Question

If you threw a switch in New York City, how long would it take the current to reach Los Angeles?

 

 

 

 

 

Answer

Electricity moves at the speed of light (186,282 miles per second), so if New York City is 2,446 miles from L.A., an electric signal would take just over one one-hundredth of a second to travel between the two cities.

However: There is an assumption that the two cities actually have a circuit wired between them that includes a power source, the switch, and the light. Otherwise the correct answer is NEVER" or will not happen.

Also, it will depend on which side of the circut is switched, "Hot or Neutral", "+ or -".
