Unformatted text preview: L , loads an EMF source and when R L is equal to the internal resistance of the cell, r, ( i.e. R L = r ). What is the terminal voltage, V T , in terms of the emf source, E ? 4) Write an equation to determine the terminal voltage of a cell, V T using the terms L std , L T and E std....
