In the nonlinear part of the component Ohm'a law does not work. Ohm's Law isnot an universal law, and is only true when the ratio of voltage to current isconstant over a wide range of voltages and, then, only for that range of voltages. In other words, if the voltage to current ratio results in a
straight-line graph. If the graph is curved, then the ratio of voltage to current is not constant, and Ohm's Law doesn't apply. So Ohm's Law doesn't apply to metal conductors such as tungsten, to electrolytes, or to electronic devices such as diodes, etc

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
