One of the principles of great importance in electric circuit design is the maximum power transfer theorem between a power supply and a load. In an electric circuit, Rh is the regulating resistor and R is the load resistor that we want the maximum power transferred to. The power transferred to the load resistor is given off by P= I^2 (R). Here, I is the current in the new circuit. Show( using calculus or otherwise) that for maximum power transfer, the condition must be Rh=R.
