It has been generally accepted that the electrical field sets up in a circuit at the speed of light. Well then, for once, imagine an LED connected to a button kept 3 lakh kilometers away. The voltage is high enough to overcome the resistance of the wire. Now if I keep on sending pulses through the circuit by opening and closing the switch at rate of 1 pulse per second (i.e. switch is closed for just half a second), what will happen to the LED? Will it blink? Or will be stay put like the Ahmedabad traffic signals on Sundays?
Keep thinking guys...
Cheers!!!

whether it blinks or not is dependent on the perception of the viewer
