Chances are that some of you say that electric current flows very fast, even at the speed of light. This is impossible with the naked eye because the electrons are photons, electrons have mass and travel much slower than 0.3 meters per nano second (speed of light).
Assuming that we use and light a lamp 100W, 100V to 1 Ampere, according to the formula the current is moving at about 8 cm per hour . Yes, I was right. However when you light a lamp that is connected via cable 8 meters (to put a number), you do not have to wait 100 hours until the garment.
This is because metals are filled with electrons, if an electron is pushed from one side (8 cm per hour), the final electron moves instantly. Therefore the electricity flows very quickly, even if the current power moves very slowly.
formula that says the speed is
I
--------- Speed \u200b\u200b= S * ρ
Where I is the current flowing through the driver, s is the section Cable and rho is the resistivity of the material.
