Hello ,

Here we go,

The answer for question number 1 is as follow,

ammeter is a device which is used to measure electric current flowing through a wire. Ammeter is connected in series.

Answer for question number 2 is as FOLLOWS,

The rate of flow of charge is known as electric current.

when one coulomb of charge is flowing for 1 SECOND in an electric wire then one ampere of current is flowing through it.

The SI unit of current is ampere or A.

I = c/t

Here I is equal to current C is equal to 1 coulomb or charge and t is equal to time.
