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 How much time is required for 10 coulombs of charge to flow past a point if the rate of flow (current) is 2 amperes?
How much time is required for complete decomposition of two moles of water at anode using 4 amperes current?
How much current must there be in a circuit if 100 coulombs flow past a point in the circuit in 4 seconds?
