    Answer: charge Q = 40Coulombs

    Explanation: The current in a circuit is the quantity of charge that flows through it per second.

    Here the 2amp current is same as the amount of charge in coulomb that flows through the terminal in ONE second.

    So, if 2 coulomb of charge flows in 1sec then in 20 secs we will have

    Q (charge) = 2*20 = 40 coulombs
