Consider the 30 ? resistor. First compute the Thevenin equivalent circuit as seen by the 30 ? resistor. Compute the value of R that results in Thevenin equivalent resistance equal to the 30 ? resistance and then calculate power delivered to the 30 ? resistor. Now let R = 0 ?, 110 ?, and ?, calculate the power delivered to the 30 ? resistor in each case. What can you say about the value of R that will result in the maximum power that can be delivered to the 30 ? resistor?
