Would a light bulb's current and voltage change according to ohm's law?
What do you think?
For the light bulb (assume it's an incandescent bulb) to be ohmic, what can you say about a specific property of the bulb?
Hint: random thermal motion may affect electron current motion...
it will work by ohm law, but R is not a constant in such equation, the resistance changes as a function of the temperture.
Tuvia, this is clearly a standard textbook question, and our posting guidelines clearly forbids writing out answers to such questions, especially if the OP has not shown any original effort.
Do you think the two posters above you didn't venture an answer because they don't know?
