Linearity Properties

  1. Oct 15, 2007 #1
    I've been presented with a question, but I am not sure how to approach it:

    A linear resistor containing two sources drives a 100ohm load resistor. Source #1 delivers 250mW to the load when source #2 is off.
    Source #2 delivers 4W to the load when source #1 is off.

    My question is, how would I go about finding the power delivered when both sources are on?

    I know that the answer isn't 4.25W, because that would just be the sum of the two powers, and disregarding the resistor.

    Thanks for your help.

    What is a "linear resistor containing two sources"? I'm not able to picture what you are asking.

    The linear part just means basically that it is a simple circuit (has additivity and proportionality)

    As for the two sources, it could be a power or voltage source, atleast if my understanding is correct.
