CURRENT2

"As mentioned above, the ""defined"" current flows from the positive terminal of the current source, trough the load, to the negative terminal of the source. Consequently, inside the ""source"" (whether it is electromechanical or electrochemical) the current must flow from the negative terminal to the positive terminal since there must be a complete circuit. This concept is especially important in electrochemistry because an electrochemical cell can be either a current ""source"" (galvanic cell) or a ""load"" (electrolytic cell). Furthermore, a rechargeable battery operates as a ""source"" during discharge and as a ""load"" during charge. "
