Thanks to everyone for all of the helpful (and insightful) responses!

Well P = I^2 * R so if current is constant, greater R would reflect more power (since R is in the numerator in the equation). I was confused because P = V^2/ R as well (although in this case, current is not in the equation and not being held constant).

Okay I understand now that I cannot make broad generalizations. Would you (or someone else) be able to confirm whether my conceptual understanding of the two bolded scenarios (holding potential constant, holding current constant) is correct?

I understand that generally, power and light bulb brightness are directly proportional. However, because there are so many ways to write the power formula (P=IV = I^2 * R = V^2 / R), I was a bit confused about what factors actually determine power and wanted to confirm whether the following is...
