- You have a faculty position at a community college and are teaching a class in automotive technology. You are deep in a discussion of using jumper cables to start a car with a dead battery from a car with a fresh battery. You have drawn the circuit diagram in Figure 2 to explain the process. The battery on the left is the live battery in the correctly functioning car, with emf ε and internal resistance RL, where the L subscript refers to “live.” Its terminals are connected directly across those of the dead battery, in the middle of the diagram, with emf ε and internal resistance RD, where the D subscript refers to “dead.” Then, the starter in the car with the dead battery is activated by closing the ignition switch, allowing the car to start. The resistance of the starter is RS. A student raises his hand and asks, “So is the dead battery being charged while the starter is operating?” How do you respond?What is the power in watts of a 2.40 ✕ 102 MV lightning bolt having a current of 1.87 ✕ 104 A?Using Kirchhoff's Current Law, determine the unknown currents for the networks shown in Figure Q1(a). 6 µA 2 µA Y0.5 µA Figure Q1(a)
