What is meant by electric current ? Name and define S.I. unil In a conductor electrons are flowing from B to A. What is the direction of conventional current ? Give justification for your answer. A steady current of 1 Ampere flows through a conductor. Calculate the number of electrons that flow through any section of conductor In 1 second. (Charge on electron ` 1.6 xx 10^(-19) C) `

Explanation

Definition of Electric current : Refer Quick Review S.I. Unit of Current-ampere Definition of t Ampere : Refer Quick Review Direction of Current from A to B Justification: Refer to Quick Review
`I = (ne)/(t) implies n= (Ixxt)/(e)`
`=(1Axx1s)/(1.6xx10^(-19)C)=6.25xx10^(18)`
