Answer 3

Drift velocity is the velocity of a charged particle inside a conductor. Drift velocity is much slower than the observed effect of current since electrons cannot travel very far in a conductor without colliding with other atoms. Also electrons do not take a straight path through a conductor. When electrons are under the influence of an external electric field, they have a net displacement opposite direction of the field. This displacement over time is the drift velocity.

Answer 4

he drift velocity is the average velocity that a particle, such as an electron, attains due to an electric field. In general, an electron will rattle around in a conductor randomly at the Fermi velocity. An applied electric field will give this random motion a small net velocity in one direction.

When a DC voltage is applied the electrons will increase in speed proportional to the strength of the electric field. These speeds are on the order of millimetres per second. AC voltages cause no net movement since the electrons "wiggle" back and forth in response to the alternating electric field.

Drift velocity is calculated using the formula:
v(d) = I / (n q A)
where:
I = current
n = number of charge carriers per unit volume
q = charge of the charge carriers
A = cross sectional area
