Calculating Power in Linearity Properties with Two Sources

Click For Summary
SUMMARY

The discussion focuses on calculating the total power delivered to a 100-ohm load resistor by two sources in a linear circuit. Source #1 provides 250mW when Source #2 is off, while Source #2 delivers 4W when Source #1 is off. The total power when both sources are active cannot be simply summed to 4.25W due to the linear properties of the circuit, which require consideration of the interaction between the sources. Understanding the principles of linearity in circuits is essential for accurate power calculations.

PREREQUISITES

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"?

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.
