Question

Current electricity​

Answer 1

Answer:

An electric current is the rate of flow of electric charge past a point or region. An electric current is said to exist when there is a net flow of electric charge through a region. In electric circuits this charge is often carried by electrons moving through a wire.

where R is the electrical resistance of the conductor and R = Ane2 τ / ml. The obstruction offered by any conductor in the path of flow of current is called its electrical resistance. Its SI unit is ohm (Ω) and its dimensional formula is [ML2T-3A-2].

Answer 2

electric current is movement of electron through a conductor
