# Define current. Give its S.I. unit. - Science

Define current. Give its S.I. unit.

#### Solution

The rate of flow of charge through a conductor is known as current. If a net charge Q, flows across any cross-section of a conductor in time 't', then the current I, through the cross-section is, "I" = "Q"/"t". Its SI unit is Ampere (A).
