If `2.25 xx 10^(20)` electrons pass through a wire in one minute, find the magnitude of the current flowing through the wire?

A 230 V, 115 W filament lamp works in a circuit for 10 minute . What is the current flowing through the bulb ?

A uniform field equal to 1.5T exists in a cylindrical region of radius 10.0cm, its direction parallel to the axis along east to west. A wire carrying current 7.0A in the north to south direction passes through this region. What is the magnitude and direction of the force on the wire if : the wire intersects the axis.

If a current of 0.5 ampere flows through a metallic wire for two hours, then how many electrons flow through the wire?
