(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Using symbols, write P_{RL}, the power dissipated in R_{L}as a function of R_{L}(your other symbols are R_{0}and the power supply voltage epsilon both of which are constant. 10V and 100ohms) and then take the derivative of this function with respect to R_{L}for which P_{RL}has an extreme value, in this case a maximum.

2. Relevant equations

V = IR

3. The attempt at a solution

So here's what I was thinking...

P_{RL}= VI where I = V/R so replace that with Epsilon^{2}/R_{0}

Then plug in the constant values 10V and 100ohms to get P_{RL}= 1W dR_{L}

Not sure where to go from here though as the derivative gives zero. What am I missing? Did I do it all incorrectly? Thanks in advance!
