    Light Brightness Relationship with Potential and Current

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

    Light Brightness Relationship with Potential and Current

    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).

    Light Brightness Relationship with Potential and Current

    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?

    Light Brightness Relationship with Potential and Current

    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...
