Electric current In a conductor Is due to the flow of charge, is the conductor charged?

Electric current is the flow of charges along a defi nite direction and take place through metals as well as semiconductors.Mention the charge carriers in the above cases.

When potential difference is applied between the ends of conductor the electrons will flow through the conductor with a constant average velocity:-Name the velocity.

When potential difference is applied between the ends of conductor the electrons will flow through the conductor with a constant average velocity. A potential ‘V’ Is applied across a conductor of length l . Keeping the potential difference same, the length of the conductor is halved. How does the velocity of electrons change?

An electric current is flowing due south along a power line. What is the direction of magnetic field (i) above it and (ii) below it ?

A current of 6A is flowing through a conductor. Calculate the charge flowing through the conductor in 5 minutes?
