Batteries connected in a series circuit cause the voltage (V) to increase, resulting in a corresponding increase in current (I). Introduce the topic. Review definitions of keywords, as well as the topics mentioned in the Background section.
A volunteer will measure the voltage across both the battery and the resistor/light bulb. Students predict the result of adding a second battery in series and measuring the total voltage. After observing this, students predict what the voltage would be if one of the batteries were turned around.
In this hands-on electronics experiment, you will connect batteries in series and learn the relationship between the individual battery voltages and the total series voltage. Connecting batteries in series, as shown in Figure 1, means connecting them in line with each other so that there is but a single path for electrons to flow through them all.
In summary, a series circuit is defined as having only one path for electrons to flow. From this definition, three rules of series circuits follow: all components share the same current; resistances add to equal a larger, total resistance; and voltage drops add to equal a larger, total voltage.
Your model says that when a battery is connected to a complete circuit, there is a current. For a given battery, the magnitude of the current depends on the total resistance of the circuit. In this investigation you will explore batteries and the potential differences (voltages) between various points in circuits.
Batteries connected in a parallel circuit increase the available current (I), but do not change the voltage (V). Batteries connected in a series circuit cause the voltage (V) to increase, resulting in a corresponding increase in current (I). Introduce the topic.
