High Quality Content by WIKIPEDIA articles! In electronics, a current divider is a simple linear circuit that produces an output current that is a fraction of its input current. Current division refers to the splitting of current between the branches of the divider. The currents in the various branches of such a circuit will always divide in such a way as to minimize the total energy expended. This can be shown by calculus. The formula describing a current divider is similar in form to that for the voltage divider. However, the ratio describing current division places the impedance of the unconsidered branches in the numerator, unlike voltage division where the considered impedance is in the numerator.
