2. Cells in Series and Parallel Dry cells can be connected together into two basic types of circuits: series circuits and parallel circuits. Series circuits: (cells in series) The advantage of connecting cells in series is that it increases the electric potential (voltage) produced at the output terminals of the batteries: as the electron travels through the consecutive batteries, it gets an additional boost of energy increasing its voltage.

3. In a parallel circuit, cells are connected side by side, or in parallel to increase the electric charge. the electron flow through only one cell before passing through the load (resistor). Therefore, the electric potential (voltage) of the electron remains the same as if there were only one cell in the circuit… But the duration of time the load will operate is directly related to the number of cells in the circuit. Ex:* With two cells there is twice as much electric energy available; therefore the load can operate twice as long before running out of energy.

4. Cells in Series and Parallel

5. Series and Parallel Circuits (10.13) There are 2 basic kinds of electric circuits: Series and Parallel.

6. Series Circuits Series: circuit is wired in one single path. Ex: Christmas lights, if one bulb burns out, all the lights have to be checked to find the burned out bulb.

7. Parallel Circuits Parallel: Circuit passes through separate circuits called branch circuits. Because each bulb is connected to its own branch circuit, it does not affect the other bulbs.
