What speed do they mean when they talk about the speed of propagation of electric current in a conductor?
May 28, 2020 | Education|
The propagation velocity of an electric current in a conductor is almost close to the speed of light in vacuum (300,000 km / s) – this is the propagation velocity of an electric field along the entire length of the conductor, although the speed of the electrons proper is small – a few millimeters per second.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
