Explain mobility of conductor and derive equation of mobility.

Explanation

`rArr ` Conductivity of material due to mobile charge carrier insider the conductor.
`rArr` In metals electrons are mobile charge carrier.
`rArr` In electrolyte positive and negative ion are charge carrier.
`rArr` In ionized gas electron and positive ion are charge carrier.
`rArr` In semiconductor electron and hole are charge carrier.
`rArr` Mobility : Drift velocity per unit electric field is called mobility .
`therefore mu = (|v_(d)|)/(E) `
mks unit `(ms^(-1))/(Vm^(-1)) = m^(2) V^(-1) s^(-1)`
CGS unit = `cm^(2) V^(-1) S^(-1)`
Dimensional formula = `|M^(-1) L^(0) T^(2) A^(1)|`
`(((m)/(s)))/((N)/(C)) = (m)/(s) xx (C)/(N)`
`(m)/(s) (C)/([kg ""(m)/(s^(2))]) = (CS)/(kg)`
= C.s. `kg^(-1)`
