# 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 ampere flows through a conductor. Calculate the number of electrons that flows through any section of the conductor in second. (Charge on electron coulomb).

## The direction of conventional current is A to B, i.e. opposite to the direction of flow of electrons. In a metal, flow of electrons carrying negative charge constitutes the current. Direction of flow of electrons gives the direction of electronic current by convention, the direction of flow of positive charge is taken as the direction of conventional current. Charge  For coulomb, electrons # Find the current following in the following circuit View solution # One billion electrons pass from a point P towards another point Q in s. What is the current in ampere? What is its direction?

View solution # The RMS value of current over a complete cycle for a current variation as shown by the graph is
