Define the term 'drift velocity' of charge carriers in a conductor and write its relationship with the current flowing through it. |
|
Answer» Solution : Drift velocity of CHARGE carriers in a CONDUCTOR is defined as that average velocity with which chargecarriers drift in the presence of an external electric field. Current` I=n Aev_d` , where n=number density of CONDUCTION ELECTRONS, A=cross-section area of conductor and e=charge on an electron. |
