Maximum Power With a Dependent Source

Random numbersTHEVHard

The dependent current source carries 1.4 vab1.4\,v_{ab} milliamperes, where vabv_{ab} is the output voltage in volts. A load resistor RLR_L is connected across aa–bb and chosen to receive the most power. Find that maximum power, in milliwatts.

Answers within 2% are accepted. Units with SI prefixes work too, like 0.003 A or 3 mA. Use a minus sign for negative values.
