Answer 1

Answer:

Ohm's law does not hold good under all conditions as it is not a fundamental law of nature like Newton's law. It is obeyed by metallic conductors only when physical conditions like temperature etc. are kepi unchanged. It is not obeyed by a lamp filament, junction diode, thermistor etc.
