# What is the speed of electricity per second?

## What is the speed of electricity per second?

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.

How do you calculate the speed of electricity?

The equation: = cm/sec = ________I_______ Q * e * R^2 * pi = . 0023 cm/sec or 8.4 cm/hour [ This is for 1.0A in #12 copper wire. ] [ Higher currents give faster drift, ] [ and thinner wire gives faster drift. ]

Which is faster than light?

Albert Einstein’s special theory of relativity famously dictates that no known object can travel faster than the speed of light in vacuum, which is 299,792 km/s. Unlike objects within space–time, space–time itself can bend, expand or warp at any speed.

### Is current same as speed?

Current is related to the speed of electrons but it is not the speed of electrons! Current is the amount of charge that passes through a cross sectional area in one second. Relating current solely by the speed of free electrons is wrong.

Can human travel at speed of light?

So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. So, light-speed travel and faster-than-light travel are physical impossibilities, especially for anything with mass, such as spacecraft and humans.

How many miles per second does electricity travel?

A: Electricity travels at the speed of light, which is 186,000 miles per second. This is because electricity is electromagnetic radiation just like light.

#### How fast does electricity travel through a wire?

How Fast Does Electricity Travel? Electricity travels at the speed of light, which is 186,000 miles per second. This is because electricity is electromagnetic radiation just like light. Electricity is the flow of electrons through a conducting wire such as copper and aluminum.

What is the speed of electromagnetic waves in meters per second?

Signal Velocity. However, the speed of an electromagnetic wave varies with the properties of the medium in which it travels. The waves the electrons radiate travel at 300 million meters per second in a vacuum, but they would travel at the same speed in a conductor only if its structure or geometry permits.

What is the average speed at which electrons move?

The average speed at which the electrons move down a wire is what we call the “drift velocity”. Even though the electrons are, on average, drifting down the wire at the drift velocity, this does not mean that the effectsof the electrons’ motion travels at this velocity.
