a$.$ Determine R$($Th$)$ and E$($Th$)$ for the network external to the $2$kOmega resistor.

b$.$ Calculate the power delivered to the $2$k resistor using the Th$$venin equivalent circuit.

c$.$ Is the power calculated in part $($b$)$ the maximum power that can be delivered to a resistor between terminals a and b$?$ If not, what is the maximum power that this network can deliver to a load?
