However, Battery A is at power level 3 and Battery C is at power level 4. So even though their run-times are the same, Battery C has a higher power level than Battery A. Batteries with the same power levels can also have different run-times. Now look at Battery B. Of the three batteries, Battery B has the highest run-time of 12 Ah.
Voltage is the energy per unit charge. 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.
Solution. We start by making a circuit diagram, as in Figure (PageIndex{7}), showing the resistors, the current, (I), the battery and the battery arrow.Note that since this is a closed circuit with only one path, the current through the battery, (I), is the same as the current through the two resistors. Figure (PageIndex{7}): Two resistors connected in series with a …
