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
