Question

Define these terms

Electric current

Drift velocity

Relaxation time ​

Answer 1

Answer:

electric current is defined as the no. of charges passing through a point per unit time.

drift velocity is defined as velocity of any charged particle under an applied electric field.

relaxation time is defined as the time between two successive collisions.

Answer 2

Answer:

electric current is the flow of electric charges in a circuit.

drift velocity is the average velocity attained by charged particles , such as electrons, In a material due to an electric field .

relaxation time is the time interval between two successive Collisions of electrons in a conductor , when current flows .
