Why is Ohm's law not always valid?

Why Ohm's law is not applicable for nonlinear circuit?
Answer : Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it, with the proportionality constant being the resistance, i.e., \( V = IR \), where \ ... the voltage and current do not have a fixed, proportional relationship, so Ohm's law doesn't apply....

Why Ohms law is not applicable at variable temperature?
Answer : Ohm's law, which states that \( V = IR \) (where \( V \) is voltage, \( I \) is current, and \( R \) is resistance), assumes that the resistance \( R \) of a ... variable. Instead, you need to account for how resistance changes with temperature in order to understand the behavior of the material....
