Some questions about electricity?

a. An Ampere a rate ogous to velocity. One Ampere is one Coulomb / second, where a Coulomb is a measurement of electrical charge. In this case it is the amount of charge to p a point in one second. One Coulomb is 1.6022�10^19 electrons. So if there is one amp of current in a wire then 1.6022�10^19 electrons p a given point in one second
