    hello friends

    how much current will circulate in a loop in which two current sources are connected back to back without any any other elements

    It's not possible to have different flows of current in different places in a series circuit. It's just not possible. To do so would be to break Kirchhoff's current law. And all hell would break loose if somebody proved that wasn't true!

    So while you can draw it on paper, this circuit with two "ideal" current sources hooked up in series with each one providing different amounts of current cannot exist.

    EDIT: If the current sources have the same value (and direction), then your answer about the current flowing through the circuit is that value. Otherwise, it is nonsense!

    circuit current would be that of the lower valued device. The higher valued device would dump max voltage onto the line, but the lower device would continue to regulate
