Question

Drift Speed of Electrons is of the order of 10-3
ms-1, but current is established in the circuit with the
speed of Light Explain

Neha Sarin · Accepted Answer

Due to collisions between electrons and atoms, the drift
velocity of electrons in a conductor is on the order of millimeters
per second However, the speed at which a change of current at one
point in the material causes changes in currents in other parts of
the material, the velocity of proporgation, is typically about 75%
of light speed This occurs because electrical signals propagate as
a wave, with the velocity dependent on the dielectric constant of
the material

Drift Speed of Electrons is of the order of 10-3 ms-1, but current is established in the circuit with the speed of Light. Explain

Drift Speed of Electrons is of the order of 10^-3 ms^-1, but current is established in the circuit with the speed of Light. Explain
