Why current is not formed in solid conductors in absence of electric field ?

Explanation

`rArr` In solid conductors electric current can be explained as follows.
`rArr` When metallic solid are formed, valence electron get separated from their parent atoms and become free electron positive ions are grounded in definite three dimensional geometric arran gement.
`rArr` In absence of external electric field these positive ion, depending on their temperature oscillate about their mean position. Electron move randomly in space between positive ions.
`rArr` During their moHon electron collide with positive ion and due to these collision their direction keeps on changing. `
` At a given time there is no unidirectional flow of electron in particular direction in given cross- section. Hence, current is not formed.
