The electron drift speed in metals is small `(~ ms^(-1))` and the charge of the electron is also very small `(~ 10^(-19)C)`, but we can still obtain a large amount of current in a metal. Why?

A

Conducting property of the conductor

B

Resistance of the conductor is small

C

Electron number density of the conductor is small

D

Electron number density of the conductor is enomous

Text Solution

(a) In Example 3.1, the electron drift speed is estimated to be only a few mm s^(-1) for currents in the range of a few amperes? How then is current established almost the instant a circuit is closed? (b) The electron drift arises due to the force experienced by electrons in the electric field inside the conductor. But force should cause acceleration. Why then do the electrons acquire a steady average drift speed? (c) If the electron drift speed is so small, and the electron’s charge is small, how can we still obtain large amounts of current in a conductor? (d) When electrons drift in a metal from lower to higher potential, does it mean that all the ‘free’ electrons of the metal are moving in the same direction? (e) Are the paths of electrons straight lines between successive collisions (with the positive ions of the metal) in the (i) absence of electric field, (ii) presence of electric field?
