Extra Credit Problem: The current I in a given cell is given by I = E where E is the electromotive force, R is the R+r external resistance and r is the internal resistance. E and r are always fixed constants for a given cell. The power is given by P = RI. Show that for any fixed cell, the power is maximized when the internal and external resistance are equal. %3|
