How Fast Does Electricity Travel In A Wire

How does electricity travel through wire as earlier discussed what travels through the wires physically is not electricity but rather the negatively charged electrons.

How fast does electricity travel in a wire. Electricity travels at the speed of light which is 186 000 miles per second. And in 1 60 of a second it will travel back and forth by 00233cm sec 1 60 0000389cm or around 00002 in. It s the electromagnetic wave rippling through the electrons that propagates at close to the speed of light. Picture 2 parallel wires going left to right in front of you carrying energy from a battery to a light bulb.

Electricity is the flow of electrons through a conducting wire such as copper and aluminum. I will assume we are referring to a current of electrical charge traveling through a metal wire such as through the power cord of a lamp. The dimensions of the wire and electrical properties. Electricity or more correctly electromagnetic energy is transferred as a vector product of the electric and magnetic field.

This word is very general and basically means all things relating to electric charge. 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 2 however the electrons themselves within the wave move more slowly. Electricity travelling through a wire moves at an extremely fast speed and is capable of powering anything from a light bulb to a laptop. How fast does electricity flow.

The electrons in a wire that form the electric current move very slowly. The speed of electricity really depends on what you mean by the word electricity. The electric current inside a very thin wire will be tend to be fast even if the value of current is fairly low. The second hand on a watch moves faster than the electrons.

In everyday electrical and electronic devices the signals travel as electromagnetic waves typically at 50 99 of the speed of light while the electrons themselves move much more slowly. 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 is because electricity is electromagnetic radiation just like light. Advertisement electrical energy is created by the movement of atoms containing positive negative and neutral charges.

The actual speed of electrons is about 1 2 inches. These electrons that jump from one atom to another are not firmly bound and are free to roam.
