The capacity of a storage battery, such as those used in automobile electrical systems, is rated in ampere-hours (A · h). A 50-A · h battery can supply a current of 50 A for 1.0 h, or 25 A for 2.0 h, and so on. Consider a 12.0-V battery that has an internal resistance of 0.26 Ω and a capacity of 55.8 A · h. The battery is charged by passing a 9-A current through it for 6.2 h. (a)...
employs a convention often used in circuit diagrams. The battery (or other power supply) is not shown explicitly. It is understood that the point at the top, labeled "36.0 V, " is connected to the positive terminal of a 36.0-V battery having negligible internal resistance, and that the ground symbol at the bottom is connected to the negative terminal of the battery. The circuit is completed through the battery, even though it is not shown. What is the potential difference...
