Question

explain drift velocity ..
.

. friends where r u yaar. .​

Answer 1

Answer :-

• When a battery is connected to a conductor then the electrons start moving from negative to positive direction they move with the velocity that velocity is known as drift velocity.

• It is denoted by $\sf\ V_{d}$

• It is a vector Quantity

• It depends on the magnitude as well as direction also

Why does electrons move on connecting battery ?

When we connect battery to any conductor then the electric field is created and the electrons move due to electrostatic force created there

Drift velocity is defined as the averagevelocity attained by the particles (electrons) of a given material due to an electric field which is proportional to current.

Ohm's law can be expressed in terms of drift velocity as follow: u=μE .

Where, u: drift velocity (m/s)
