Battery Internal Resistance
Low internal resistance batteries are much better at supplying high current pulses. Internal resistance also increases as the battery discharges. Therefore, a typical alkaline AA battery may start out with an internal resistance of 0.15Ω but may increase to 0.75Ω when 90 percent discharged.
21.2: Electromotive Force
Internal Resistance As noted before, a 12-V truck battery is physically larger, contains more charge and energy, and can deliver a larger current than a 12-V motorcycle battery. Both are lead-acid batteries with identical emf, but, because of its size, the truck battery ...

3.3: Networks of Batteries and Resistors
Learn how to analyze networks of batteries and resistors using Kirchhoff''s rules and the concept of equivalent resistance. This chapter covers the basics of direct current circuits, including Ohm''s law, power, and energy. Compare and contrast different examples of series and parallel combinations of resistors and batteries.
19.2: Electric Current
Thus a motorcycle battery and a car battery can both have the same voltage (more precisely, the same potential difference between battery terminals), yet one stores much more energy than the other. The car battery can move more charge than the motorcycle battery, although both are 12V batteries.
10.2: Electromotive Force
Using conventional current flow, positive charges leave the positive terminal of the battery, travel through the resistor, and return to the negative terminal of the battery. The terminal …
