5. In the following circuit, + V1 V Rx RY A) Determine the power dissipated in Ry as a function of Ry, Rx, and V1. B) Using Rx-100 and V1→ 10, construct a graph of power dissipated as a function of Ry from 0 to 1000. C) Using general variables, determine Ry in terms of Rx, and V1 that maximizes the power dissipated in Ry.
Which of the following are characteristics of series circuits? Select all that apply. There are multiple paths for current to follow through the circuit. The voltage is divided among all devices in the circuit. If one device in the circuit stops allowing current to flow, all other devices in the circuit will also stop functioning. O The voltage across each device must be the same. O There is only one path for current to follow through the circuit. The same amount of current flows through all devices in the circuit.

Hybrid vehicles are powered by a gasoline engine paired with an electric motor and batteries. Hybrids get much better mileage in the stop and go of city driving than conventional vehicles do. When you brake to a stop in a conventional car, friction converts the kinetic energy of the car’s motion into thermal energy in the brakes. In a typical hybrid car, depressing the brake pedal will connect a generator that converts much of the car’s kinetic energyinto chemical energy in a battery. Explain how this makes a hybrid vehicle more efficient.
