A battery is a cluster of cells connected together for greater voltage and/or current capacity. Cells connected together in series (polarities aiding) results in greater total voltage. Physical cell size impacts cell resistance, which in turn impacts the ability for the cell to supply current to a circuit.
If this battery of cells were powering a circuit, the current through each cell would be 1/5 of the total circuit current, due to the equal split of current through equal-resistance parallel branches. A battery is a cluster of cells connected together for greater voltage and/or current capacity.
For ease in analyzing circuits, we suggest drawing a “battery arrow” above batteries that goes from the negative to the positive terminal. The circuit in Figure 20.1.4 20.1. 4 is simple to analyze. In this case, whichever charges exit one terminal of the battery, must pass through the resistor and then enter the other terminal of the battery.

“The ions transport current through the electrolyte while the electrons flow in the external circuit, and that’s what generates an electric current.” If the battery is disposable, it will produce electricity until it runs out of reactants (same chemical potential on both electrodes).
Close the battery switch S1 and begin graphing. Observe what happens to the current through bulb A (i.e. through the battery) and the current through bulb B when the switch S2 to bulb C is opened and closed. Open the battery switch S1. Print one set of graphs for your group.
