A method of finding the internal resistance of a cell when the value is known to be high. A second cell, a galvanometer and a resistance are connected in series with the cell under test, and the value of the resistance required to give a galvanometer. deflection of half the value obtained with the cell alone is found.

The half deflection method is the method by which an internal resistance of a cell can help in evaluating value which is considered as high. Considering the second cell, is also a galvanometer along with resistance which is eventually defined as a series along with the cell under test, and estimating the value of the resistance which can charge the galvanometer. The deflection of half is considered as a value obtained along with the cell alone.
