Why Does My Car Battery Keep Dying? Lifewire The purpose of a car battery is to power the starter motor and to provide electricity to run accessories like lights and your radio when the engine is off. Once the engine is running, the charging system takes over. So if it seems like the battery is dying with the engine running, there’s probably an issue with your charging system.

Transient response of RC and RL circuits After 3˝, the circuit will have gotten 1 e 3 ˇ95% of the way, and after 5˝, more than 99%. So, after a few time constants, for practical purposes, the circuit has reached steady state. Thus, the time constant is itself a good rough guide to \how long" the transient response will take. RC Circuits Michigan State University (a) Charging (b) Discharging Figure 4.2: Schematics of charging and discharging a capacitor. Charging and discharging the RC circuit Charging Initially, a capacitor is in series with a resistor and disconnected from a battery so it is uncharged. If a switch is added to the circuit but is open, no current flows. Chapter 7, Problem 1. Faculty Server Contact Chapter 7, Problem 12. The switch in the circuit of Fig. 7.92 has been closed for a long time. At t = 0 the switch is opened. Calculate i(t) for t > 0. Figure 7.92 For Prob. 7.12. Chapter 7, Solution 12. When t < 0, the switch is closed and the inductor acts like a short circuit to dc. The 4 Ω
