An electrical signal in a copper wire moves roughly at 2/3 the speed of light in a vacuum, so, about 200,000 km/second. Since the Earth has a circumference of about 40,000 km, that means such a signal can go all around the Earth in 1/5 of a second.

What is an complete circuit?
A circuit is complete whenever current can flow from the battery (or what is producing current), through the circuit, and back to the battery. A complete circuit could contain just a battery and one wire. An incomplete circuit could be a battery with a wire attached to just one terminal, because current cannot flow all the way through the circuit in this case (i.e. cannot flow through the battery). note: not all elements in a circuit may have current flow in a complete circuit. For instance, a light bulb may be shorted but you still have a complete circuit.
Describe how a change in resistance would affect the current in a circuit?
As long as the voltage between the ends of the circuit remains constant, the current through the circuit is inversely proportional to the total effective resistance of the circuit.
What does the high specific heat of water have to do with the convection currents in the air at the seashore?
Water'specific heat capacity is 4200 J/Kg°C . This high specific heat capacity suggests that the water will travel long distances without losing heat . This makes the convection currents in the air last longer.
What are some testable questions involving electric currents?
Here I got one.. How long would it take for an electric current to travel through an 11 foot wire?
How long does it take for a poleshift to complete?
We do not know, but it is possible that we may shortly (?) know if present trends continue. We know it is not a long time in geological terms.
How long does its take the blood to complete the circuit of your body?
5 to 4 hours
What is circuit that is complete and unbroken with flowing electric current?
Yes, as long as the unbroken path is a good conductor of electricity.
What happens to a bulb when you move it to the battery on a circuit?
It doesn't matter where the bulb is in respect to the battery, as long as the circuit is complete, the bulb will light up.

A racing car driver can complete one circuit of the track in 5 minutes and 18 seconds How long should it take him to complete 25 laps?
Multiply by 25
How long is a circuit?
A circuit is just as long as a piece of string.
Is globe a short vowel or long vowel?
The word globe is a long vowel. It would be a short vowel if the word globe was spelled as "glob". Otherwise, it is a long vowel.
How long does current remain in a 220 volt circuit?
The current will remain in a 220 volt circuit as long as the circuit load remains in the circuit and the circuit remains closed.
Does the bulb light up in a parallel circuit?
The bulb will shine as long as it is still part of a complete circuit. You probably have a diagram for such a circuit. See if you can still trace a path through the battery and one of the bulbs without passing through the other bulb. For comparison, try the same thing with a diagram of a series circuit.
A security guard walks the equivalent of six city blocks when he makes a circuit around the building If he walks at a pace of eight city blocks every 30 minutes how long will it take him to complete?
A security guard walks the equivalent of six city blocks when he makes a circuit around the building. If he walks at a pace of eight city blocks every 30 minutes, how long will it take him to complete a circuit around the building, assuming he doesn't run into any thieves?
A security guard walks the equivalent of 6 city blocks when he makes a circuit around the building If he walks at a pace of 8 city blocks every 30 minutes how long will it take him to complete a circu?
(6 blocks / circuit) * (30 min. / 8 blocks) = 22.5 min. / circuit
