    I'm a little confused about the wording of this question:

    Here's the diagram:

    I used the formula: V=IR to solve the problem, but since the question stated to "assume that the resistance in the circuit is negligible compared to that of the lightbulb," I just did V=I, leading to me to answer choice C.

    What are they trying say by "assume that the resistance in the circuit is negligible compared to that of the lightbulb?" :mad:

      I forgot that the circuit, itself, can have some resistance (though it's negligible), so the question was reiterating that the resistance in the circuit, compared to that of the light bulb, is negligible...which should be assumed from usual, practical application.:idea:
