What is the relation between electron movement speed and electric current?

I.e., a cable is a form of a waveguide. The propagation of the wave is affected by the interaction with the material(s) in and surrounding the cable, caused by the presence of electric charge carriers (interacting with the electric field component) and magnetic dipoles (interacting with the magnetic field component).

What is the speed of an electron as it flows through a circuit?

Drift velocity, the average speed at which electrons travel in a conductor when subjected to an electric field, is about 1mm per second. It’s the electromagnetic wave rippling through the electrons that propagates at close to the speed of light.

What is the relationship between current resistance and voltage difference?

The relationship between voltage, current, and resistance is described by Ohm’s law. This equation, i = v/r, tells us that the current, i, flowing through a circuit is directly proportional to the voltage, v, and inversely proportional to the resistance, r.

What is the relation between electron velocity and electric field?

When a potential difference is applied across a conductor, free electrons gain velocity in the direction opposite to the electric field between successive collisions (and lose velocity when traveling in the direction of the field), thus acquiring a velocity component in that direction in addition to its random thermal …

Is electron current 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.

How does voltage affect the total current in a circuit?

The current in a circuit is directly proportional to the electric potential difference impressed across its ends and inversely proportional to the total resistance offered by the external circuit. The greater the battery voltage (i.e., electric potential difference), the greater the current.

What can be relation between the drift speed and electric field travel?

Due to this drift velocity, there is a net flow of electrons opposite to the direction of the field. When a conductor is not connected to any battery, free electrons are said to move due to their temperature and hence the name. This is the relation between drift velocity and the electric field.
