A bulb cannot be used in place of a resistor to verify ohm's law. Justify this statement with reason? A bulb cannot be used in place of a resistor to verify ohm's law. It is because Ohm's law holds at constant temperature only.

Answer:
ohm law requires that resistance must not change during the experiment (due to temperature) but during experiment as current flows ,the filament's temperature start rising so the resistance of bulb also change
hope it helps thanks
