In the two-node network shown below, the Generator produces 60 MW, which is all consumed by the load. The resistance of Line 1 (R1) is 2R, and the resistance of Line 2 (R2) is 4R. How much power flows on Line 2, in MW?

What is the pKa of a drug?

A power system has three generators: Generator A has a heat rate of 8 mmBTU/MWh, a fuel price of $3.5/mmBTU, a variable O&M cost of $4/MWh, and a capacity of 10 MW; Generator B has a heat rate of 11 mmBTU/MWh, a fuel price of $6/mmBTU, a variable O&M cost of $6/MWh, and a capacity of 15 MW; Generator C has a heat rate of 9 mmBTU/MWh, a fuel price of $10/mmBTU, a variable O&M cost of $10/MWh, and a capacity of 10 MW. All the generators have zero fixed costs. Find the marginal cost of these generators and the system lambda when the electricity demand is 24 MW.
