A battery can be modeled by a voltage source Vt in series
Chapter 2, Problem P2.94(choose chapter or problem)
A battery can be modeled by a voltage source Vt in series with a resistance Rt. Assuming that the load resistance is selected to maximize the power delivered, what percentage of the power taken from the voltage source Vt is actually delivered to the load? Suppose that RL = 9Rt; what percentage of the power taken from Vt is delivered to the load? Usually, we want to design battery-operated systems so that nearly all of the energy stored in the battery is delivered to the load. Should we design for maximum power transfer?
