The SI unit of electric current is

The rate of flow of charge in a circuit is called electric current. In other words, it is the amount of charge flowing per second. It is denoted by the letter I. If Q is the charge which is flowing through a conductor in time t, then current is given by i = Q/t Unit of current: The S.I unit of current is ampere and it is denoted by the letter 'A'. The S.I unit of Q is coulomb and that oft is second. Thus, the S.I unit of electric current is ("1 coulomb")/("1 second") = 1A If there is a current of 10 amperes in a circuit for 10 minutes, what quantity of electric charge flows in through the circuit?
