Match the following :
| 1 | Drift velocity | A | et/m |
| 2 | Electric current | B | V/I |
| 3 | Resistance | C | eEt/m |
| 4 | Mobility | D | neAvd |
Answer & explanation
Correct answer: option 3
Drift Velocity = \frac{eEt}{m}$
Mobility of the charge carrier is defined as the drift velocity of the charge carrier per unit of the electric field. $Mobility = \frac{\text{Drift Velocity}}{\text{Electric Field}} = \frac{et}{m}$
$I = \frac{V}{R} = neAV_d$
