Circuits And The Speed Of Light

Summary :

Since we know the effects of electricity do have a finite speed albeit very fast a set of very long wires should introduce a time delay into the circuit delaying the switchs action on the lamp figure below at the speed of light lamp responds after 1 second. The speed of light is related to the permeance of a given medium for the electric field and magnetic field in free space a vacuum the permeance is optimum for both the electric and magnetic fields so the speed of light is at its absolute maximum approximately 297 x 10 exp 8 meters second. Circuits and the speed of light suppose we had a simple one battery one lamp circuit controlled by a switch when the switch is closed the lamp immediately lights. Circuits and the speed of light suppose we had a simple one battery one lamp circuit controlled by a switch when the switch is closed the lamp immediately lights when the switch is opened the lamp immediately darkens figure below lamp appears to immediately respond to switch. For electric current in the home your power company supplies energy the cause of electrical shock is predominantly excess voltage the entity that travels about the speed of light in an electric circuit is electric field the electric resistance in a length of wire is doubled when the wire is
