Answered by paditji

An electric current is a flow of electriccharge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in an ionised gas (plasma). ... Electric current is measured using a device called an ammeter.
question 4
energy given to each coulomb of charge is equal to the amount of work which is done in moving it.
question 3
Calculate the number of electron constituting 1 coulomb of charge. 6.25 ⨯ 1018 electrons pass per a second across the cross section of the conductor.
question 2
Therefore 6.25 x 10 18 electronsflow per second through a conductor if 1 Ampere current is measured through it.

paditji: Therefore 6.25 x 10 18 electronsflow per second through a conductor if 1 Ampere current is measured through it.
