Problem P. 3939. (December 2006)

P. 3939. Two 100- $\Omega$ resistors are connected in series, and they are operated from a supply which generates constant voltage. A variable resistor is connected to one of the 100- $\Omega$ resistors in parallel. Find the resistance of the variable resistor when it dissipates the greatest power.
