Answer 3: Light travels through empty space at 186,000 miles per second.
The electricity which flows through the wires in your homes and appliances travels much slower: only about 1/100 th the speed of light.
What speed does electricity travel at?
In the case of an electrical cord connecting a table lamp or some other household item to a power source, the copper wire inside the cord acts as the conductor. This energy travels as electromagnetic waves at about the speed of light, which is 670,616,629 miles per hour,1 or 300 million meters per second.
Why does electricity travel at the speed of light?
Do you mean an electric signal or electrons or other carriers of charge. Electric carriers push each other using electric field which spreads with the speed of light (speed of light is the specific media, which is slower than in vacuum). Therefore the electric signal spreads with the speed of light.
Can an electron travel at the speed of light?
That means the electron is traveling at 99.9999992% of the speed of light. A calculation shows that the electron is traveling at about 2,200 kilometers per second. That’s less than 1% of the speed of light, but it’s fast enough to get it around the Earth in just over 18 seconds.
What is the speed of electricity in km per second?
In other words, the greater the distance from the conductor, the more the electric field lags. Since the velocity of propagation is very high – about 300,000 kilometers per second – the wave of an alternating or oscillating current, even of high frequency, is of considerable length.
